General Mach Discussion / cutter comp
« on: October 16, 2011, 06:53:42 PM »
I have a question about cutter comp in mach3.
I wrote a test program to cut a 1" circle with a .5 endmill
Useing centerline of the tool. So I should not need Any comp,
Only to add or subtract from the tool diameter. So under tool 1 in the tool
Table it was all zeros. It cut a 1.5" diameter hole. So I comp'd
It .250 and it cut the 1" hole. I should not have to put any comp in.
Here is the program I used, its pretty simple.
G90G54G0x.12y0.0
Z.5g43h01
Z.1
G94 g1 z-.1f10
G41 x.25D01
G17G3 I-.25 J0.0
G40 x.125
G0z.5
M30
Should I add a g40 at the top to cancel any comp??
