A axis: too many A's

[MotorCityMinion]

I'm attempting my 1st 3d contour on an A axis. Nothing too fancy. What I am getting is a ton of 3 place decimal A moves in the code. The main contour is a 180. Deg arc. Why so many A moves? Why not more ijk's? The Z depth is constant in the contour so I would figure a simple A180. or a little less would suffice for most of the code.

 

Also, where I might use a feed of 45. IPM with a .25 ball on a regular surface, in the rotary move I'm getting upwards of f1500. Does this sound about right for a rotary feed at a 3.316 dia? (inverse). Tool steel, about .01 DOC.

 

MPmaster is the post.

Adjust your filter settings and see if that helps the number A moves. F1500. is an inverse time feed rate. There have been several threads on inverse time.

WOW Coulston... that's the best technical explaination I've ever heard!

I'll mess with the filters tomorrow and see if it helps. If I can't produce code that, feed wise, works for me, I'll use the parameters in the machine to set the 4th axis diameter. Thanks for the help.
