General Mach Discussion / Re: Mach Turn Feed Per Revolution

« on: February 23, 2009, 03:19:26 PM »

If you are running in G94 feed mode then no matter what you do to the spindle speed the feed will not change when in G97 spindle mode.

If you run in G95 feed mode and G96 spindle mode then the feed and speed are locked together and the feed rate increases/decreases as the spindle speed rises and falls.

In G97 spindle mode with a feed of 1 unit per minute (G94) and a spindle speed of 1000 the feed rate is 1/1000 = .001/rev if you then drop the spindle speed to 500 rpm then the feed is still 1 unit per minute but the feed rate is .002/rev

G94 is feed per minute e.g. F1.0 = 1"  or 1 mm per minute, axis will move this distance in 1 minute.

G95 is feed per spindle revolution  e.g. F.01 = .010" or .01mm feed per rev

G96 is constant surface speed e.g. S100 = 100 feet or 100 metres/min  spindle speed, speed increases as cut diameter gets smaller.

G97 is fixed speed e.g. S1000 = 1000 revs per minute.

Yes and no.

What is the difference between typing A90. and M590 ?

You will save nothing.

You are sort of there, what you are talking about is a g-code sub program, a macro is a block of visual basic code that is called with an M code and a list of variables that can be changed on the fly. The macro in effect writes the g-code to do the function.  Macros can also be used to configure/drive machine functions, tool changers etc.

Mach will cut any shape you tell it to including rads.

Maybe I should be an engineer/machinist for a living now I have the hang of it.

Hi Vince,

what feed, speed, depth of cut & finishing allowance do you want and I will do you some code using your .125 tool, is it a ball end or a square end ?.
