Hi, I am new at this and looking for some help. I am having a prob getting a
.120 radius looking right. Its close enough, but I would still like to get it right. I am still messing with it, but here is what i have now:

stock dia is 1.75

rapid abs x1.85 z-.120
line abs x1.75z-.120
arc radius abs cw x1.51 z0. r.120 f.007
line abs x-.05 z0.

For starters, is this a correct way of turning the radius? Is it better to cut towards or away from the chuck? Also, if i change my r to .15 , the z to z-.150 and x1.51 to x1.45, the .120 r looks looks fine. I thought that this might be due to the tool nose radius, but it is set correctly (1/32) in the library.

Any help will be much appreciated.

Check to see if your tool shape is defined correctly and the touch off points are correct. Also check to make sure there is no wear entered in the table.

Here are some details to this concept. The touchoff point can get a little strange for profiling with center of radius compensation to the radius tool verses actual touchoff points.
