G Code Question

[dgoddard]

When changing the code G21 to G20 (I use ipm units) in a post processer I noticed that the writer used a G40.1 code. I know what G40 means, but what does G40.1 mean? I was unable to find this anywhere.

Thanks for the response. Have printed the chart for reference.

I noticed that chart included the G15 & G16 codes. Anyone ever use those? I used to do those on a Fanuc OM. Does anyone know of they are only in a special Fanuc package/option group?

Programming in Polar is very handy. I used it all the time when I programmed Heidenhain controls. They do a good job on Polar.

G91 G16 G17
G1 X3. Y30 F10.
G15

This will feed from the current position, 3 inches at 30°.
It's easier than doing the trig.
