General Mach Discussion / Re: Mach 3 putting in offsets? HELP!

« on: April 07, 2010, 07:29:45 PM »

Half you problem is that the code is in incremental, if it starts in the wrong place it will remain in the wrong place until an absolute command is issued.

Have you a picture of what you are trying to machine?

I am not sure what you are asking but if you reverse the direction you will reverse the thread e.g. right hand would become left hand.

G02 travelling Z zero to Z minus will produce a right hand thread (clockwise helix)

G03 travelling Z zero to Z minus will produce a left hand thread (anti clockwise helix)

In your macro you can check the input with something like this

If IsActive(Input1) Then
  msg("Clamped")
Else
  Code "M30"
End If

Or if this is something that needs to happen all the time then you can add it to the Cycle Start button script.

If IsActive(Input1) Then DoButton (0)

Not always the case,  when you run a G00 command there is no CV blending so the movement is stopped after every move command.

Daniel,

If I was cutting a square on and eccentric peg then I would use the chuck as a rotary indexer and mill the flats, why make life hard 

But the square code is doable too.

This is why you need a Y axis

The code is the easy bit the hard bit is getting a machine that can follow the code instructions,  you need the X or Y axis to be in sync with the spindle.  Then the code is generated using Sin and Cos of a selected arc length on a offset centre point, the Z movement is then divided into the number of cords.

If you make the conforming machine I will write you the code.

Clive,

if its a repeat job bore a offset hole in a round billet and split it through the thick side then you can hold it in the three jaw.

You would need a lathe with a Y axis for a start so you could maintain the tool centre height.

Mach3 has no looping macro commands.
