Introduction This tutorial will illustrate machining of a simple prismatic part such as this gasket using 2-1/2 milling operations. Even though we have created a 3-D representation of the gasket, it will be seen later on that we can machine this using just 2-D curves. The reason we are able to do this is because of the prismatic nature of this model. The stepped instructions are accompanied by explanatory and introductory text. Reading this text will help you understand the tutorial methodology and provide information about additional options available. Don’t forget to save your work periodically! You may want to save the file under a different name so that the original file will be preserved. Strategy to Machine the Gasket
• We will machine the Gasket by using a 2-½ axis machining operation called Profiling.
• The part will be machined out of a 8 ½ x 5 x ¼ inch poplar wood sheet using a ½ inch Flat End Mill.
• The wooden sheet will be held to the machine table or the spoil sheet on the table using double-sided tape.
Main Programming Steps In creating programs for each setup, the following steps will be followed:
• Create the Stock geometry • Set the Machine zero point or Locate geometry with respect to the machine
coordinates • Create / Select the tool used for machining • Set the feeds and speeds • Set the clearance plane for the non-cutting transfer moves of the cutter • Select the machining regions for containing the cutter to specific areas to cut • Select the machining operations and set the parameters • Generate the toolpath • Simulate the toolpath.
You may have to repeat either all or part of these steps for subsequent operations.
Preparing the part for Machining Loading the Part Model “Part” refers to the geometry that represents the final manufactured product. You can create parts within Rhino.
To load a part:
1. Select File / Open from the Menu, or click the Open icon from the Standard bar.
2. From the Open dialog box, select the Gasket.3dm file from the Tutorials folder in the RhinoCAM 2.0 installation folder. (C:\Program Files\Rhinoceros 4.0\Plug-ins\RhinoCAM 2.0\Tutorials)
The imported part appears as shown below
Note: You can import solid models, Stereo-Lithography (both ASCII and binary) format files. Surfaces can be imported from IGES, STEP or Rhino 3DM. Faceted (triangulated) models can be imported from VRML, Raw Triangle, DXF / DWG facet data, or Rhino Mesh.
4. Select Post from the setup tab to specify the post processor options
5. Set the current post processor that is on your controller. We will select Haas as the post processor for this exercise. Set the posted file extension type to .nc
Note: By default post processor files are located under
2. This brings up the Box Stock parameters. Set the Length (L) = 8.50, Width W = 5.00 and Height (H) = 0.125. Leave the other parameters as default and Click OK.
3. The stock geometry is now created, and a semi-transparent stock box is displayed on top of the part geometry.
2. Under Set WCS Origin, choose Set to Stock Box, the Zero Face to Highest Z, and Zero Position to South West corner. This sets the machine home to the top of the stock material and the southwest corner of the part geometry.
Note: You can change the stock model transparency under standard mode by selecting Simulation Preferences that is located at the bottom of the MOps browser.
Align Part and Stock
In this process, we can align the part and the stock geometry. As we have set the Machine zero to the Stock Box, we will now move the part relative to the stock.
1. Select Align Part and Stock from the Setup tab
2. Set to Object to Move as Move Part, Z alignment to Top and XY alignment to Center
The part geometry is aligned to the center of stock in XY and top in Z. Click Save to save the work and specify a file name as Gasket-Rev1. The file is now saved with extension 3dm.
Create Tools To machine the above part we will now create a ½ inch (0.5”) Flat End Mill.
1. Go to the RhinoCAM-Tools browser that is located below the RhinoCAM-MOps browser and select Create/Edit Tools. Select the Tool Type to Flat End Mill.
You can assign Feeds & Speeds to a tool or you can load from a table. In this exercise, we will assign feeds and speeds to the tool.
3. Switch to the Feeds & Speeds tab inside the create/select tool dialog.
4. Use the following settings for feeds and speeds.
5. Click Save as New Tool. The tool is now created and listed under Tools in Library. Click OK to close the dialog.
Note: You can edit the tool properties and click Save Edits to Tool to save the changes. You can create additional tools by assigning a different name and specify the tool parameters.
The created tools are now listed under the RhinoCAM-Tools browser.
5. The command bar will now prompt the user to select surfaces or faces for duplicate border.
6. Select the top face (surface) on the Gasket. A selection list will display the geometries that can be selected. Browsing through the selection tree will highlight the surface that corresponds to the selection.
This brings up the 2 ½ Axis Profiling Operations dialog. We will go over the steps for creating the profile operations for the inner features of the Gasket.
Select Machining Features/Regions 2. Go to the Machining Features/ Regions tab and click Select Curves as
6. Switch to the Tools tab inside the 2 ½ Axis Profiling operation.
7. Select the FlatMill-0.5. The 0.5” Flat End mill is now selected as the active tool and the Tool parameters are displayed to the right of the Tools window.
11. Set the Clearance Plane Definition to Automatic and Cut Transfer Method to Clearance Plane.
RhinoCAM will determine a safe Z height for the Entry & Exit when set to automatic. Setting Cut Transfer to Clearance Plane would apply the automatic Z clearance between transfers when the tool moves from a machining region to another.
13. Set the Stock = 0 and under cut start Side check Use Outside/Inside for Closed Curves and select Inside. Alternatively you can also use Determine using 3D model.
14. Select the Cut Levels Tab and specify the Total Cut Depth = 0.125. The cut depth is always set as an absolute value.
Shop Docs Shop documentation can be generated selecting Machining Operations under the Create Operations tab. Right mouse click and Shop Documentation. User can select from one of the 2 templates and generate shop documentation. This is saved as an html file and can be printed and handed over to the operator in preparation for the part to be machined on the CNC.
The post by default is set to Haas as specified under the Post processor setup. You can change the post processor by selecting a different one from the drop down menu in the list. The posted g code by default will be saved to the folder where the part file is located.
This tutorial will introduce the usage of 2 ½ axis profiling and Engraving Machining Operations of RhinoCAM. We will be using the Gear.3dm part file.
It should be noted that, even though the part file contains a 3-D geometry representing the part, we could machine this entirely by using just 2-D curves due to the prismatic nature of this model. The stepped instructions are accompanied by explanatory and introductory text. Reading this text will help you understand the tutorial methodology and provide information about additional options available. However, if you prefer to work straight through the steps without any additional reading, look for the following symbol:
Don’t forget to save your work periodically! You may want to save the file under a different name so that the original file will be preserved. Strategy to Machine the Slotted Gear
• We will machine the gear completely using 2 ½ axis-machining operations. • We will use the Profiling operation to cut the outer shape of the gear and the
Engraving operation to cut the slots. The engraving option is preferred in situations where the cutter can be driven to create a slot that conforms to the shape of the tool trajectory. This is because of the computational efficiency as well as the accuracy of this method.
• The part itself will be machined out of a 3 inch x 3 inch x ½ inch poplar wood sheet.
• The wooden sheet will be held to the machine table or the spoil sheet on the table using double-sided tape.
• The part will be machined using a single ¼ inch flat end mill. Main Programming Steps In creating programs for each setup, the following steps will be followed:
• Create the Stock geometry • Set the Machine zero point or Locate geometry with respect to the machine
coordinates • Create / Select the tool used for machining • Set the feeds and speeds • Set the clearance plane for the non-cutting transfer moves of the cutter • Select the machining regions for containing the cutter to specific areas to cut • Select the machining operations and set the parameters • Generate the toolpath • Simulate the toolpath.
You may have to repeat either all or part of these steps for subsequent operations.

15. Select the Cut Levels Tab and specify the Total Cut Depth = 0.25, Rough Depth/Cut = 0.125. This would cut the profile in 2 cuts of each 0.125”. Make sure the cut level ordering is set to Depth First. This would profile the inner circle and then the outer profile.
To exit the Simulation mode, pause the Simulation, and click Exit Simulation. This switches back to the Create Operations tab.
Creating an Engraving Operation
Now we will use engraving operation to cut the slots of the gear by driving the 0.25 inch tool in the slot. As already mentioned, the most efficient way of machining slots is to use the Engraving option and drive the cutter along the center of the slot.
1. Switch to the Create Operation tab.
2. Select Engraving from the 2 ½ Axis operations menu.
The post by default is set to Haas as specified under the Post processor setup. You can change the post processor by selecting a different one from the drop down menu in the list. The posted g code by default will be saved to the folder where the part file is located.
Introduction This tutorial will illustrate machining of a prismatic part such as this Shaft Base using 2-1/2 milling operations. Even though we have created a 3-D representation of the part, it will be seen later on that we can machine this using just 2-D curves. The reason we are able to do this is because of the prismatic nature of this model. This tutorial will introduce the usage of 2 ½ axis machining for a simple one sided part. We will use profiling, pocketing and hole pocketing operations. The stepped instructions are accompanied by explanatory and introductory text. Reading this text will help you understand the tutorial methodology and provide information about additional options available. Don’t forget to save your work periodically! You may want to save the file under a different name so that the original file will be preserved. Strategy to Machine the Shaft Base
• We will machine the shaft base completely using 2 ½ axis-machining operations.
• The starting material for the Shaft Base is soft wood and the size is 5.5 x 3.25 x 0.75 inches.
• The wooden sheet will be held to the machine table or the spoil sheet on the table using double-sided tape.
• The part will be machined using a single ¼ inch flat end mill. • Determining the sequence of machining operations
o As the part thickness is 0.625” thick and the available stock is 0.75” the first operation would involve reducing the thickness of the stock over the entire area from 0.75 to 0.625. To carry out this operation we will use the 2 ½ axis Facing Operation as the toolpath extends past the region.
o The next step would involve machining the areas around and inside the boss. As the thickness of material to be removed is not the same for both the areas we would have to use 2 separate operations to clear the material. We will use 2 ½ axis Pocketing Operation which is ideal removing material inside a specified region.
o We are now down to the level where the step holes need to be machined. As the holes are circular we will use 2 ½ axis Hole Pocketing operation to machine the holes to its depth in 2 separate operations.
o The 2 inner holes can be drilled using an engraving operation to its depth.
o Finally we will cut out the shape of the part from the rectangular using a contour toolpath. This is accomplished using a 2 ½ axis Profiling Operation which separates the finished part from the stock material.
Main Programming Steps In creating programs for each setup, the following steps will be followed:
• Create the Stock geometry • Set the Machine zero point or Locate geometry with respect to the machine
coordinates • Create / Select the tool used for machining
• Set the feeds and speeds • Set the clearance plane for the non-cutting transfer moves of the cutter • Select the machining regions for containing the cutter to specific areas to cut • Select the machining operations and set the parameters • Generate the toolpath • Simulate the toolpath.
You may have to repeat either all or part of these steps for subsequent operations.

Introduction This tutorial will illustrate machining a Sign using 2-1/2 axis-engraving operations. We can engrave the sign using 2-D curves. This tutorial will introduce the usage of 2-½ axis simple V Carving using V bit. V carving refers to a cutting strategy employed by sign makers to create sharp corners. V carving is performed using a tapered bit or conical tool (as shown below) usually known in the industry as a V Bit.
The V-bit is made to rise from the cutting depth to the top of the surface at the corners in such a way that the tapered sides of the cutter are always in contact with the corners. When the cutter finally reaches the top surface, only the bottom tip of the tool will be in contact with the corners, thereby creating clean and crisp cuts at the corners. The stepped instructions are accompanied by explanatory and introductory text. Reading this text will help you understand the tutorial methodology and provide information about additional options available. Don’t forget to save your work periodically! You may want to save the file under a different name so that the original file will be preserved. Strategy to Machine the part
• V carving is performed using the 2 ½ axis Machining Operation. • The part itself will be machined out of a 10.75 inch x 4 inch x ½ inch poplar
wood sheet • The part would be machined using a single V-Groove bit. • The wooden sheet will be held to the machine table or the spoil sheet on the
table using double-sided tape. Main Programming Steps In creating programs for each setup, the following steps will be followed:
• Create the Stock geometry • Set the Machine zero point or Locate geometry with respect to the machine
coordinates • Create / Select the tool used for machining • Set the feeds and speeds
• Set the clearance plane for the non-cutting transfer moves of the cutter • Select the machining regions for containing the cutter to specific areas to cut • Select the machining operations and set the parameters • Generate the toolpath • Simulate the toolpath.
You may have to repeat either all or part of these steps for subsequent operations.

Introduction This tutorial will illustrate machining this Ring using 4 axis-milling operations. This tutorial will introduce the usage of several 4-axis operations such as 4 axis roughing and finishing. The stepped instructions are accompanied by explanatory and introductory text. Reading this text will help you understand the tutorial methodology and provide information about additional options available. Don’t forget to save your work periodically! You may want to save the file under a different name so that the original file will be preserved. Strategy to Machine the ring
• We will machine the ring completely using 4 axis-machining operations. • The part itself will be machined out of a cylindrical blank. • The stock will be held to the machine table using a rotary chuck. • The part will be machined using 0.0625” and 0.03125’ ball end mills.
Main Programming Steps In creating programs for each setup, the following steps will be followed:
• Create the Stock geometry • Set the Machine zero point or Locate geometry with respect to the machine
coordinates. • Set the rotary axis and rotary center. • Create / Select the tool used for machining • Set the feeds and speeds • Set the clearance plane for the non-cutting transfer moves of the cutter • Select the machining operations and set the parameters • Generate the toolpath • Simulate the toolpath.
You may have to repeat either all or part of these steps for subsequent operations.
Preparing the part for Machining Loading the Part Model “Part” refers to the geometry that represents the final manufactured product. You can create parts within Rhino.
To load a part:
1. Select File / Open from the Menu, or click the Open icon from the Standard bar.
2. From the Open dialog box, select the RingExample_2.3dm file from the Tutorials folder in the RhinoCAM 2.0 installation folder. (C:\Program Files\Rhinoceros 4.0\Plug-ins\RhinoCAM 2.0\Tutorials)
3. Set the Machine type to 4 axis and Rotary Axis to X axis. For most controllers rotation along X represents A axis and rotation along Y represents B axis. We will set the Rotary Center once we determine the Machine Zero.
4. Select Post from the setup tab to specify the post processor options.
2. This brings up the Cylinder Stock parameters. Set the Axis (rotary) = X, Radius = 0.48” and Length (L) = 0.4. Leave the other parameters as default and click OK.
3. The stock geometry is now created, and a semi-transparent stock is displayed on top of the part geometry.
4. You must switch the simulation model to Polygonal model to run 4 axis simulations. Select Preferences->Simulation Preferences from the Setup Tab and switch the simulation model to Polygonal if set to Voxel.
1. The steps below help you determine the machine home (also know as machine zero or tool touch off point) for the part/stock geometry.
2. Select Locate WCS from the Setup tab.
3. Under Set WCS Origin, choose Set to Stock Box, the Zero Face to Highest Z, and Zero Position to East. This sets the machine home to the top of the stock material and the right most edge of the part geometry.
Note: You can change the stock model transparency under standard mode by selecting Simulation Preferences that is located at the bottom of the MOps browser.
Align Part and Stock During this step, we will align the part inside the stock geometry.
1. Select Align Part and Stock from the Setup tab
In this step, we will position the part to the center of the stock in XY & Z.
2. Use the following settings, Object to Move: Move Part, Z alignment: Center and XY Alignment: Mid-East.
Specify Rotary Center In this step we will determine the rotary center for the part geometry. The rotary center must pass thro’ the entire part geometry. RhinoCAM will not compute a toolpath if the part/feature is below the rotary center as this is considered as an undercuts in the part.
1. Select Machine Setup from the setup tab. In the above example, the stock diameter is 0.96”.
2. Set the rotary center in X and Y = 0 and Z = -0.48 which is the center of the stock geometry.
The rotary center is represented by an arrow and displayed on the part geometry when the Machine Setup Dialog is invoked.
Create Tools To machine the above part, we will now create 0.0625” and 0.03125” Ball End Mills.
1. Go to the RhinoCAM-Tools browser that is located below the RhinoCAM-MOps browser and select Create/Edit Tools. Select the Tool Type to Ball End Mill.
2. Set the tool name as BallMill-0.0625, Tool Diameter = 0.0625 Flute Length = 1” and Tool Length = 1.5”. Under the Properties tab, set Tool Number = 1.
5. Click Save as New Tool. The tool is now created and listed under Tools in Library.
Note: You can edit the tool properties and click Save Edits to Tool to save the changes. You can create additional tools by assigning a different name and specify the tool parameters.
6. Create a 2nd Ball End Mill with the following parameters.
a. Tool Name: BallMill-0.03125, Tool Number = 2.
b. Switch to Feeds & Speeds tab set Spindle Speed = 5000 rpm, plunge, approach & engage feed = 20 ipm, cut feed = 30 ipm, retract and departure feeds = 20 ipm. Set the Transfer Feedrate to Use Rapid.
c. Click Save as New Tool.
The created tools are now listed under the RhinoCAM-Tools browser.
Create Machining Operations We will machine the ring using 2 different machining operations – 4 axis Roughing and Finishing. The first step in machining the ring will be a roughing operation. In this cut method, the tool cuts the stock in successive levels. The spacing between these levels are specified by the user. This type of machining is very efficient for removing large volumes of material and is typically performed with a large tool. Roughing is typically followed by semi-finishing or finishing toolpaths.
Switch to the Create Operations tab in RhinoCAM-Mops browser.
If the rotary center is not set to the same location as the Machine Zero, a warning message dialog would be displayed at all times when a 4 axis machining operation is selected. Users can override this message by clicking OK in the dialog.
Note: You can check Do no show this dialog again to stop the warning message appearing again when you create/edit a 4 axis machining operation.
2. This brings up the 4 Axis Roughing Operation Dialog. We will now go over the steps for creating the toolpath.
3. Switch to the Tools tab inside the 4 Axis Roughing operation and select BallMill-0.0625.
4. Click on the Feeds and Speeds tab and select Load From Tool. RhinoCAM will now get the feeds and speeds information that was set when the tool was defined.
4th Axis Roughing operation #2 We will now create a second 4 Axis Rough operation to machine the pocket areas around the ring by limiting the toolpath using start, end angle cut containments. Copying a MOp
1. Switch to the Create Operations tab in the Mops Browser. 2. Select the 4 Axis Roughing operation, right click copy. 3. Now right click and select paste.
4. A copy of the rough operation is created below the 4th Axis Roughing
operation. The operation name is labeled 4th Axis Roughing-1 and is as shown below.
Specify Cut Parameters 5. Double click on 4th Axis Roughing-1 to edit the operation.
6. Switch to the Cut parameters tab and use the following parameters. a. Leave the global parameters and cut pattern unchanged b. Under Cut Containment change the Start Angle (S) = -90, End
Specify Step Down Control 8. Use the Following Settings.
a. Cut Levels, Check Top (T) and specify Top (T) = 0.4 (as we had limited the toolpath to a radius = 0.4 on the 1st Rough operation), Step Down Control (dR) = 75 (% Tool Diameter).
9. Click Generate. The 4 axis Roughing toolpath is now generated, and the Operation is listed under the RhinoCAM-MOps browser.
4th axis Finishing We will now use 4th Axis Finishing operation to finish the part using a 0.03125” Ball End Mill.
In this method, the tool is always normal to the axis of table rotation (continuous mode). The tool motions can be parallel to or normal to the rotation axis. From the Create Operations tab, select 4 axis Milling and 4 Axis Finishing.
This brings up the Finishing Operations dialog. We will go over the steps for creating the pocketing operation.
1. Switch to the Tools tab inside the 4 Axis Finishing operation dialog and select BallMill-0.03125.
2. Click on the Feeds and Speeds tab and select Load From Tool. RhinoCAM will now get the feeds and speeds information that was set when the tool was defined.
3. Switch to the Clearance Tab and set the Clearance Plane Definition to Automatic and Cut Transfer Method to Clearance Plane.
5. Set the Tolerance to 0.001, Stock to leave =0, Cut Pattern = Along Axis, Zig Zag, Low to High, Set Cut Containment Low Value = -0.4, High Value = 0.01, Step over distance = 10 (% Tool Diameter).
6. Click Generate. The Finishing toolpath is now generated, and the Operation is listed under the 4 Axis Roughing Operation in the RhinoCAM-MOps browser.
1. Select Machining Operations from the Create Operations tab and right click and select post process.
2. Specify the File Name as Ring2.nc and click save.

Introduction This tutorial is intended to describe the 4 axis pocketing and hole making operations. Pocketing machines closed regions as if they were pockets - completely enclosed by inner and outer regions. The tool cannot go beyond the outer region, and cannot go within inner regions. This is unlike Facing, in which the outermost region is considered to enclose material to be removed. Hole making operations are used to create holes in a part; the hole types varying from simple drill holes, counter sunk holes, through holes to tapped and bored holes. Here you will learn to drill simple holes. The stepped instructions are accompanied by explanatory and introductory text. Reading this text will help you understand the tutorial methodology and provide information about additional options available. Don’t forget to save your work periodically! You may want to save the file under a different name so that the original file will be preserved. Strategy to machine the part
