General Mach Discussion / MachTurnNo2

« on: July 11, 2014, 11:55:10 AM »

I have an Orac lathe converted to Mach several years ago, the computer hard drive failed, I have since got a used computer with XP and loaded Mach also the C11.xml file that I had a copy of.
As I have not used the lathe for years, and my memory on how to use it is fuzzy, in manual mode the spindle runs, but I can’t get it to jog, tried with jog on and jog mode on and off.
I think there is something simple I am not doing? I have attached the xml if that helps
Could someone advise please?
Thanks

Mike

Thats good news as I have been buying secondhand PC's with XP as back up machines when a problem occurs like I just had!!

Thanks

Problem solved, it’s been a long time since I needed to change settings I couldn’t remember the procedure. The hard drive on my computer which has run the mill for years started playing up so had to change over to spare machine.
MS are not supporting XP anymore; will Mach be available to work with more up to date operating programs?
Thanks again

General Mach Discussion / Problems with Y axis

« on: April 11, 2014, 01:36:20 PM »

My origional computer started playing up so swaped over to another one, when I started to run a program the Y axis moved in a minus direction the x and z where ok. I checked ports and pins for motor settings they seem ok. Both computers are useing the same xml, here it is, can you check if all is well.
Thanks

Brilliant! it works a treat, by altering the A axis dia and X length you can create desired pitch of worm. CNC capabilities always impress me.
Thank you very much for this valuable information.

Thanks for your suggestions however does not solve the problem, I have found a way of producing a very coarse thread by using G0 rapid code and reducing kernel speed to 100 so X and A axis turn together at a reasonable feed to run a milling cutter. A four start worm can then be made buy making an angled cutter to suit the pitch.
Industry mill worms using a rotary axis so there must be a way of controlling the two axis independently?

I am trying to make a  4tpi 0.850” dia worm gear, my lathe is not big enough to handle the forces generated, so I thought I could thread mill on my CNC mill using the fourth axis rotary table.
Problem is how do I control A axis and X axis independently while on the same line of code i.e.?
G1 A360 F30 X1.00 F6
Or is there another G code command to cover this situation? I have looked through G codes but can’t find one that suits.

Thanks

Problem solved, X axis slide gib stip was loose adjusted the screws so no slop in table and now cutting to size
Thanks for your help

Typo, size should 0.010" must of been thinking about the MDI test

As I siad I have been useing ArtCam for years and nothing I do has changed, ArtCam has a tool menu like all Cam packages, you input the size be it inch or mm and it shows the size in decimil

Ian
The total is 1.00" as the part I am cutting is both sides, and new cutter, as I said the kernel speed is what it normaly is, that was the idea of the MDI test.
