Tool retract/Approach within the centre of circle!!!!
Posted: Mon May 28, 2012 8:27 am
I want to make grooving toolpath in exchanger tubesheet hole. I am using 2D profiling toolpath and want the tool to enter and retract from within the center of the hole but my tool does not retract and approach within the center. I have made many changes in lead in lead out angles, retract approach length settings but all in vain.
Consider my FaceMill tool is 17.2mm diameter with the tip of 3mm i.e. groove width., and the groove circle is 20.3mm diameter.
I am unable to make a toolpath to enter the tool from the exactly at the centre and retract exactly from the centre of hole? the retract and approach is just off-centre say 0.1mm etc...
I have generated the Gcode and changes the entry /retract cumbersomely in NC editor for a single hole but for lot of holes it will take a lot of time to manually change the gcode.
Any thought help?
