QuatroMill with Heidenhain TNC 355 control

Post by Steve » Mon 27 Nov , 2006 13:32 pm

We have a customer who has purchased a QuatroMill with Heidenhain TNC 355 control.

Does anyone know the following?

On my quatromill ( recently purchased secondhand ) what commands are used to rotate the 4th. axis?

The controller is Heidenhain TNC 355.

I want to be able to rotate the 4th. axis continually at about 100rpm.

I would expect that the 4th axis is controlled with a go command and then an end angle and speed. I would not think that it would be possible to index the axis continuously.

Hi Steve - sorry for late reply - been away for a few days n just got back!

4th axis on a Heidenhain would be programmed just like any other axis. The actual axis letter used is defined in parameters but I expect it to be the 'A' axis (but could be 'B' or 'C')

It would be programmed like this (remember the Heidenhain usually uses it's own Dialog style NC code)...

A Linear move to A90 @ 300mm/min...
L A90 F300
Incremental Linear...
L IA90 F300

You can't get the axis free running, it must be an interpolated move with an final end point, before the control moves onto the next block, but you can interpolate with other axes...

L X300 A360 F300
(X Axis moves 300mm whilst rotary axis moves 360 deg)

Hope this helps and Good Luck

:shock:
