C Manufacturing Verification in a nutshell

C Manufacturing Verification enables easy validation of machining processnd analysis of the accuracy of machined parts. This product detects andports collisions between the tool/tool holder and stock/fixture in a graphirm. It also identifies machining operations and tools responsible for theserors. NC Manufacturing Verification helps analyze the accuracy of machin

arts by detecting gouge and remaining material. These results are displaya graphical form with the innovative use of color contours on the machin

art. Tools to analyze machined parts geometrically are also provided.

C Manufacturing Verification seamlessly provides analysis and validationpabilities to NC Manufacturing. It provides tight interaction between tool

ath generation, simulation (material removal) and edition.

efore reading this guide

efore reading this guide, you should be familiar with basic Version 5 concech as document windows, standard and view toolbars. Therefore, wecommend that you read the In fra s tru ctu re Us e r's Gu ide that describes

eneric capabilities common to all Version 5 products. It also describes theeneral layout of V5 and the interoperability between workbenches.

Comparing the Machined Stock Part and thDesign Part

This procedure describes how to do a comparison between the machined stock anthe target (design) part through the graphical comparison functionality in Video.

Areas on the machined stock from which extra material has been removed arereported as g o u g e s . Areas where material has not been removed completely arereported as r e m a in in g m a t e r ia l.

This functionality provides a visual comparison achieved by color-coding the stockaccording to how close the machined surface is to the surface of the target (desigpart. A series of tolerance bands and a color for each band is defined. All points othe machined surface that lie within a particular band are given the correspondingband color. By defining the tolerance band appropriately, all remaining materialpoints or gouge points on the machined surface can be identified and displayed inmany colors.

The magnitude of remaining material or gouge can also be queried at a specifiedpoint. This magnitude is the shortest distance between the picked point on the stoand the nearest point on the target (design) part. The coordinates of the pickedpoint on the stock are also displayed along with the magnitude of remaining mateor gouge.

Complete the procedures as described in Accessing NC Manufacturing Verification

1 . In the Replay dialog box, select the Full Video icon to simulate the materi

removal by the machining operation previously selected in the PPR tree. (For

more information, see "Video Mode for Material Removal Simulation" in the NCMan u factu rin g In fra s t ru ctu re Us e r Gu ide .)

21/67

The new display fields are Arc radius and Arc center. Thesefields are displayed only if the picked point is on a circular

entity.

This information is available at every pick provided that the pointpicked is a "machined area pick". To get information about errors andeviation at the picked point, you first need to do a design partcomparison. Design part comparison will render the stock in a color-

coded manner, depicting deviations from the design part. A subseque

pick will display the deviation value.

P o in t / P o in t Measures the distance between two points. Thecoordinates of both points are also displayed.

Ed g e / Ar c Measures the distance and angle between an edge aan arc center axis if the edge is parallel to the arccenter axis. If they are not parallel, only the anglebetween them is measured.

Ed g e / P la n e Measures the distance and angle between an edge aa plane if the edge is parallel to the plane. If they arnot parallel, only the angle between them ismeasured.

Ed g e / P o in t Measures the shortest distance between an edge anda vertex. The coordinates of the point on the edgefrom which the minimum distance is calculated is alsdisplayed.

P o in t / Ar c Measures the shortest distance between the arc centaxis and the vertex.

P o in t / P la n e Measures the shortest distance between a point and

plane

During the material removal process, chunks of material may getdetached from the stock. You can pick any of the unconnected materbelonging to the stock and delete it after the simulation has been

stopped. This functionality eliminates false collisions that occur whenunwanted chunks remain after being detached from the stock.

1 . In the Replay dialog box, select the Remove Chunks command.

The Delete Material dialog box appears.

2 . In the 3D view, select the parts to be deleted. The select partschange color.

3 . Click OK in the Delete Material dialog box. The unwanted materiadeleted.

This procedure describes how to define maximum machining feedrate for a part operation as well as for

specific machining operation.

From the samples directory, open the Processfinal.CATProcess file or you may use your own data.

Defining for a part operation

1 . In the PPR tree, double-click on Part Operation.1.

The Part Operation dialog box appears.

3 . Input the desired value in the Max machining feedrate field and click on OK.

Errors (tool collision with the stock) will be reported if the feedrate exceeds this value.

Defining for a specific machining operation

1 . In the PPR tree, double-click on Tool Change.1

The following dialog box appears:

2 . In the dialog box, click on the button. The dialog box expands. The maximum machining

feedrate can be set in the Feeds & Speeds tab. Errors (tool collision with the stock) will be reported ithe feedrate exceeds this value.
