How do I synchronize 4th axis speed with X,Y,Z?

[buscht]

I ran this command;
G01X6A60F60
The machine responded exactly as Gerry predicted, the A axis turned 60 degrees in one minute and moved 6" in one minute. Again, assuming a 4" dia part, 12.5664" in circumference that would give me 2.09" per minute speed going around in the A axis.

I tried
G01X6A60F600, The speed went to 60" per minute in the X and 20.09" in the A. Not exactly in sync, but closer to the overall performance that I wanted.

It looks like I would have to not program in degrees, but map the A axis to Y and use linear movements to get matching speeds.

Other than that, I should stick with just using the A axis as an indexer.

Its not a big deal to me, I just want to make sure I understand what is and isn't possible and then work with those parameters.

Thanks

A Cam system is best in figuring out the appropriate departures and feedrates for
moves involving rotary axeses.
The Feedrate is based on the length of the move considering all axses per geometry
involved.
Because the position of the rotary axes in relation to x,y,z may vary between
different machines the Cam system has to be configured for a specific machine
in order to do this correctly.
Good Luck
