Lead in/out

[Smrkoul]

I have problem when machinig 2D contour.

If i select cutter compensation computer, toolpath is OK.

If i select cutter compensation control, tool will cut into material (lead in radius is missing, lead out radius is on wrong side-cut to the material).

I tried to change lead in/out line lenght, radius lenght, entry/exit point, but nothing happend.

Can you help me please?

If you want to use cutter compensation with the "Control" setting, you need to use a line and an arc that are greater than 50% of your tool diameter. Otherwise the lead in move will fail. In backplot you need to make sure that "simulate cutter compensation" is turned on and Mastercam will simulate the moves the machine will make.

 

If your cutter is cutting on the wrong side of the chain, you either need to change the compensation side (right or left) or you need to reverse your chaining direction

 

To do this: Expand the operation, click on "geometry", In the chain manager dialog box, right-click on the chain and select "reverse chain" in the menu. After reversing your chain you may need to change the compensation side (right or left) again.

 

Hope that helps and welcome to the Forum,
