4th axis tolerance

[Candyman]

Hi all,

where would i find the tolerance value that my 4th axis breaks its angle moves into?

thanks

This is controlled in two places. First the machine definition rotary axis has an angle resolution that defines the actual increment that the indexer can position to. Second, if you are using a multiaxis toolpath each will have its own settings of how to post the angular rotation movements. Please give some more info about your setup if you need something more specific.

I want to produce a cylinder with a single rotary axis command of 360°. How can I prevent mastercam from breaking my moves up?

 

I am driving a single circle in 5 axis curve with another single larger Ø circle controlling my tool axis.

 

I tried setting maxium step to 100", turned distance increment off, turned angle increment off, and turned filtering off. I have tried several different values in these settings as well.

 

I have used axis sub in the past to get cleaner motion, but I am posting this thru CAMplete and I do not get the same result using axis sub. Is there a way to get 360° moves out of a mutli axis TP with the right settings?

I would say that the multiaxis toolpaths will always output multiple linear moves (and increasing the maximum step will probably only make those moves longer) so you would probably have the best chance of doing this with axis subs.

 

Here is a quick example that I hope looks good in Camplete (never used it myself)
