All,

I am trying to Face Tap on a Mori Seiki CL-203B Machine. The machine goes in fine to the -0.625 point and then will not reverse the spindle and feed out.

I get the EX0401 ( G1027) SPINDLE OR ROTARY TOOL SPINDLE ON ALARM.

The section of the program is:


T0808
S150 M03
G00 X0.0 Z0.5
G84 Z-0.625 R-0.1 S150 F0.07692
G00 G80 Z1.0


Any light shed on this will be greatly appreciated. There is no good example of the G84 in the Mori Programming book. This alarm is also not listed.

Thanks

Hutch

This is a Mitsubishi Meldas Control.

Don't know about your Mori but on our Nakamura Tomes (Fanuc) we have to issue a M29 command first for rigid tapping. Looks like this:

M29 S150
G84 Z(depth) F(feed)
G80

Hope it helps.

Not_In_Use THanks, I will try that.

I did write the code out long hand ;

I CHANGED MY ZERO POSITION. The face that gets tapped starts at Z-0.500.

G00 Z-0.25
M03 S150
G63 (Tapping)
G01 Z-0.800 F0.0769
M05
G04 P0.1
M04
G01 Z-0.1 F0.0769
M05
G64
M03



This works which makes me think it has something to do with the machine reversing from M03 to M04.

I still have not found anything on this MSC-803 Mori/Mitsubishi control

FYI, no live tooling, no rigid tapping on that machine.

Is there a machine parameter that would cause this?

FROM THE PARAMETER MANUAL

CONSTANT ERROR


The time constant has not been set or the
setting exceeded the setting range.
