Automatic verification shank clearance issue

[clifford.gage]

Hi I'm having a problem when I am trying to finish areas with a small rad .

The tool I am using is 2mm with a shank of 1.8mm so I have a clearance of 0.1mm each side

But if I have the collision checking on and even have the shank clearance a 0.00, it won't cut past the depth of the cutter.

I need to have the collision checking off, or I have noticed if the shank is 1.6mm, it will work with a shank clearance of 0.06.

bit annoying because I don't want to have to change the shank size because I would like to see what the real tool size doing, is case it will crash somewhere, plus the shank starts to taper so I need that to stop within 0.08mm if the pocket gets deeper.

Collision off:

Collision on:

It thinks it is colliding here:

It clearly isn't:

I've attached the program. I'm thinking I maybe have some setting on somewhere not allowing a shank within 0.16mm or something . But I can't seem to work it out.

Any help would be much appreciated.

Thanks

Cliff

Hello,

The tolerance of the toolpath directly influences the final result.
I suggest decreasing the tolerance to 0.02mm and using 0.04mm for the collision check.
The actual clearance must be greater than the toolpath tolerance.
I have attached the amended project.

Ha brilliant, easy fix then.
