G96 Not working on T32
I have a Mazak SQT 15MS (new to me). Just started using it. The problem is when I programme Eg.
N1 T0101 M03 G96 S100
N2 G50 S2000
The Controller is T32-3 and the spindle speed slows down as the diameter gets smaller and gets faster as the diameter gets bigger. The exact opposite of what it should do. I expect it's a parameter issue. But can't find it yet. On my other Mazak T32-2 it works fine. Any ideas ?
Another thing is using the driven tooling. Any feed rate I programme it ignores and uses a feed rate from a parameter I think. How can I change this to programme a feed rate and get it to use it ? I know I have to use G97 for the driven tooling but that's ok I just want to be able to select a feed rate.
Thanks in advance,
sounds like hosed up parameters here and there.
Mazak has an inside PC app called 'parameter compare' that allows you to compare any two machines with the same control.
This is beautiful for finding clearly bogus parameters.
The 3-axis EIA programming book usually has clear programing examples for all scenarios in G code.
In the states, the 'boys in Kentucky' have made up 'programming templates' for G code scenarios. These days it mostly applies to the esoteric E machines and Integrexes. Mill turn has been around for 20 years, so Mazak assumes everybody 'knows it already' and it's so simple it's almost self-evident'.
ONE TRICK for mastering G code, THE WAY MAZATROL LIKES IT, is to go to the COMMAND SCREEN, create MODEL MAZATROL PROGRAMS - for mill turn, sub spindle pick off, etc. These programs will be merely to create your own G code templates for frequent programming events for your machine type.
SINGLE BLOCK YOUR MAZATROL PROGRAM, and write down each change on the screen. You will have the G coding of the mazatrol, eventually. Mazatrol, as I understand it, post processes mazatrol programs down into G code to commands right to the machine buffer, but MAZAK made this as invisible as they possibly could, possibly to maintain that ole' mazatrol magic?.
I'm a former Mazak Apps tech in the USA and it was the policy in our office to embrace any Mazak, regardless of where it came from or how old it was. It was also the policy to provide free phone support for anybody with a Mazak. I hope they do the same where you are!
