cutter compensation

[sheldon]

Hi All,

when i use a contour toolpath using cutter comp. on the haas machine it gives an error and the progrom doesnot run but when i verify in mastercam the tolpath runs.i had changed the lead in and i had also put the arc move greater than then the tool diameter.can your help me in this problem.

 

Thanks

You need your G41 to be on a straight line.

Do you have that?

Sheldon you need a Leaner line for the cuttuer comp to work and if for example you make it a leaner line of .02 and try and comp for .025 you will get this alarm.

If you code line has ij call outs on it that means it is probably a G2 or G3 arc command, and many controls will not accept cuttercomp on an arc. It must be a linear move ie. G1. HTH

 

I had this problem when going from fadal to fanuc control. The Fadal had no problem with cuttercomp being on an arc move, the fanuc said no no. I had to change my programing style and defualt operations accordingly.

Try going into your Lead In/Lead Out and changing it from tangent to perpendicular and see if that helps.
