Re: Using round profile inserts on a lathe

Re: Using round profile inserts on a lathe

In Intercon F9 Setup what is the G71/G72 Rough Angle Escape Angle set to? 45 or 90 If set to 45 that may be why you are seeing the angle. Would send a report and the Intercon file so we can see what your setting are and how the program is written. With a pocket like this for the finish pass I have f...

Re: Thread milling with single point tool question

The tooling company will give you the range for the threads per inch (pitch for metric) so the shank will not rub the ID on internal and OD on external. You need to check the thread mill is size correctly for the threads you are cutting. If you are doing a harder material and want to make a semi rou...

Your Question : Can you use the spindle nose as the datum for setting up your tool offsets? (and Probe offset) I use the spindle nose here at the Centroid shop in Curwensville.

Re: CNC LATHE POST PROBLEMS

Uwe correction will fix the problem. The fish hooks, what we call them here at Centroid, ( your wording inverted arc) happens when cutter comp is turn on or off, in your case turn off and there is not enough travel in X or Z to allow for the nose radius to be compensated for to the next move. Most t...

Re: Z Offset Issue with Rear Approach Tools

Your primary approach is always positive for X for gang tooling. If the Primary approach is Rear then X will be positive for the rear mounted tools and X Diam will be positive. If the Primary approach is Front then X will positive for the front mounted tools and X Diam will be positive .

Re: Setting X Offset for ID tools on the lathe

Uwe,

I believe this is a bug that was reported before. I you change tool Orient to FFace and it measures correctly with the X Diam set to positive then this is a bug that is being fixed in the next rev. .
