Turning offset toolpath and simulation issues

[jschoenhalsBEGJ3]

There are a few issues I am running into with turning.

First, when simulating a facing operation with 'in control' selected for the compensation type it will generate normal tool path data and display that toolpath correctly, but during simulation the toolpath will be displayed offset from the front of the part and the tool will follow this offset path, leaving stock on the front of the part.

Second, Groove tools have been giving me a real headache. For a simple parting operation, a similar issue as above happens. With the 'in control' setting I will have good toolpath data except for an extra Z move as the tool is feeding out which is not present with 'wear' or 'in computer' selected. Then, an offset toolpath is displayed and I get a really wonky toolpath in the simulation. 

I also use the profile finishing operation for turning and parting the back of more complex parts. With 'in control' on it creates toolpath data that is offset in the negative Z direction by the tool's groove width. But, there is two sets of toolpaths in the toolpath data window (see pic) and the second set is correct, but when I post the operation it has the offset first toolpath.

P.S Instead of Z0.0 in facing ops Fusion always has a VERY small but non zero number but it always posts as Z0.0

Interesting, I'm seeing the same. I've not used "In Control" in many years, so I'm unsure if this is a new issue. I've reached out to the Turning team to see what their thoughts are on this.

Oh, and to close the loop on this: the duplicate data in "Show Toolpath Data" is expected when using In Control Compensation, and we do something similar for canned cycles as well (drill and turning).

For the simulation issue, this does appear to be limited to OD turning tools that have been oriented along the axis of the part. I've opened up CAM-53896 to investigate the issue, thanks for reporting it

If anyone is having the same problem and finds this post, I have found a good workaround to get toolpaths that let you use your machine's tool nose radius compensation. In the tool library, set your tool's nose radius to 'custom' and enter zero. Use 'wear' compensation in the operation. This has worked for me to generate good toolpaths.
