Hello all,
I have a weird toolpath problem which I want to share.
I want to machine a half sphere with 250 mm radius, with mastercam and 85 mm endmill.
I choose waterline toolpath, when the machine starts to machine the part, it goes in circles machining the part, all seems to go fine, BUT all suddenly the tool does not follow the circlular path as it seems in backplot and goes STRAIGHT IN the sphere damaging the part and stop the machine.
Any ideas?
