Forming Material Terminology
• Ductility - ability to be elongated in one dimension while becoming thin in another dimension
• Elastic Limit - point at which material will not return to original shape
• Plastic Deformation - stretching metal enough to exceed its elastic limit and stopping prior to fracture
• Spring back - amount which material tries to return to its original shape after forming

Machine Considerations
• Sheet Gap– Definition: measurement between the top of a new
die and the bottom of a new punch in the forming position.
– Trumpf = 55.80mm
• Ram Operation– Hydraulic

What Limits Form Height?
• Machine Limitations– Trumpf recommends a maximum of 25mm
for form height. – This is a tool limitation, not a machine
limitation
• Material Limitations– An emboss stretches material– Some forms bend material like lance and
form– Material ductility– Form geometry

Programming Considerations
New Models (600 & 1000 series)
• Programmable ram heights• Customer can tell machine
tool length and depth• Necessary for
sheetmarker, rollerball
Old Models• No programmable ram• Require shimming• Tool positoning – 4 different
pin settings

66
Programming Considerations
500 Models • Programmable ram heights
– Not as flexible as newer models– Step-by-step like old models
• Not able to program tool length and depth• Not able to run sheetmarker, rollerball

Forming Tools Set-Up Information
• Older Machines– Length settings
• Pin positioning
• Die shims
• Newer Machines– Length settings
• UT-Offset (LDP Value)
– Forming position• OT-Offset (forming
mode) - height that form tool goes to after the form is made

What is the LDP Value?
• Linear Displacement Parameter (LDP)• Also known as UT Offset• Length setting• Necessary for newer models
– TC600 and 1000 series

LDP Calculator
Available in Excel file
Machine requires tool length measured from top of alignment ring to bottom of form

Set-up Information
• Necessary for our customers to use Mate Forming Tools.
• We deliver the same Set-up Information as Trumpf.• We send the information together with each forming tool
and sample sheet.• Pass/WT do not consistently send Set-up Information.

Set-up Information
• What information does the Trumpf customer need?– What is important for the programmer?– What is important for the operator?

1212
Programmer
• He has to put the tool in the tool library before making the NC-code.
• Needs the following tool information:– Tool type (forming tool type 13)– UT-Offset (LDP)– Tool Length (example: 31,50mm)– Hole Diameter– Material Thickness

1313
Operator
• The operator has to put the tool in the tool library before making the NC-code.
• The operator needs the following tool information:– Tool type (forming tool type 13)– Tool Length (example: 31,50mm)
© 2010 Mate Precision Tooling. All rights reserved.PPT00030_Trumpf_Training_Pt1_Basics_RevA/07/26/2010
1414
Operator
• The operator cannot call up the punching program unless the tool is physically available at the machine.
• When all tools are available, the ToPs program is transferred to the Siemens control on the punch press.
NOTE: ToPs is Trumpf propietary software – other softwares may be used on Trumpf machines and terminology may vary

1515
Operator
• After the punching program is in the Siemens control, the operator can modify the tools one at a time.
Example: penetration or stroke settings
• These changes are made in the PTT table (tool library) on the machine.
