toolpath with cutter radius compensation
PostPosted:Thu Sep 18, 2008 8:25 am
Hi, I'm a new user of PartMaster Mill level 3. Is there any way to get toolpaths with cutter radius compensation (for expl. RL or RR (Haidenhain iTNC530) or G41 or G42 (ISO)) without pathoffset. If tooloffset is aktivated in PartMaster the toolpath is the aequidistance of the contour. Then the machinecontrol will offset the toolpath again. How can I fit this problem? In postprocessor or in Partmaster? Can you help me?
Thanks a lot!

Within the 'GOROUND' dialogue box there is an 'Options' tab.
When this Tab is selected the resultant page shows a series of
options one of which is :-
PART SURFACE PROGRAMMING (PSP)
If this option is selected then the original geometry path is output
with the relevant CRC supporting code (usually G41/G42 or RL in
the case of Heidenhain conversation codes).
The post processor can be modified to always output CRC codes
regardless of whether or not PSP is selected.
If you are using re-ground tools and wish to offset by the tool
variance then you would wish to output the Offset Path with CRC
When PSP option is selected all Offsetting is carried out by the CNC
controller and the user is constrained by the rules of the controller.
e.g. Some controllers require an Approach move which is greater
than the diameter of the tool, this move is where the CRC is applied.
I know of a case where an 80mm dia tool was being used and the
Controller demanded a 98mm approach move to apply CRC.

Thank you for your answer! Now it works well!
