adpative clearing problem with boss diameter

[j4872]

Not able to determine why the circular  boss is larger than  specified .518 inch + 005. The actual diameter left is well over.6 inch

Have tried 2 d adaptive and 3d with same results. Have adjusted geometry with no success. No forums topics found covering this issue.

Have verified the design specs are correct. Would appreciate any suggestions? File attached.

Thank you,

Judge

Hi

Adaptives are ROUGHING toolpaths and depending on your machine and how fast you are feeding you may end up with excess stock due to machine inaccuracies, tool deflection etc.

The toolpath is correctly leaving the 0.05(you said 0.005 but you have 0.05 in stock to leave) stock to leave

0.518+0.05*2 = 0.618

but again it a roughing toolpath, you need to run a 2D contour or similar to achieve truly accurate results, especially on hobby type machines which you may have due to the Mach4 post I see selected.

Thank you for quick response. Looked at .05 several times..thinking had set .005..dumb mistake
