Fanuc /Makino riggid tapping

[DavidB]

I have Makino machines here that need a M135 before the tapping cycle (G84).

I did a program for a mate on his Fanuc 16i it needs a M29 to sync the spindle.

Why is the coding different?

Is it a Makino thing?

Is the M29 standard for Fanuc and Makino change it to M135 for there Pro3 controllers?

 

Thanks

M29 is everyone else, just about and the M135 must be a Makino thing. You sure Makino is not made by Fadal, everything just haaaasssss to be difeerent

Our Kitimura has a 16i control and M29 turns the

chip conveyor off.

Methinks the Fanuc 16 + can be set by parameter to automatically use rigid mode for G84 or, use M29 + G84 for rigid , G84 for standard tension/compression.

Rigid Tapping has two components that control this on a Fanuc.

 

1) The PMC

2) Parameter Settings

 

The PMC for every Fanuc is written by the Machine Tool Manufacturer.

The PMC is what is used to establish the Miscellaneous Function Code (M-Codes) among many other things.

 

Parameters may also exist that should allow you to Rigid Tap without the M-Code.

 

Fadal's manual shows that you that an M-Code is required for Rigid Tapping.

It isn't.

 

Simply output without turning on the spindle with an M03.

G84 G98 X0.0 Y0.0 Z-0.75 R0.5 S800 F40.0

 

I'm willing to bet that you may be able to do it in a similar fashion.

Consult your parameter manual.

In the Fanuc manual for the 16i it says G84 is tapping and M29 before the G84 is rigid tapping.

 

The Makino book says G84 standard tapping (G84) for floating holder (G74) for reverse tapping.

M135 is the rigid tapping command.

 

M29 on the Makino is Unconditional power off

The Kitimura takes a G84.2 to rigid tap,a G84

is regular tapping,I found that out the hard way.

David,

 

M135 is a specific makino M code, There are a number of them M135 M319 M741 etc etc

[?Mark]

Somebody here gave me a little lesson some years ago (can't remember who) that G codes are control specific and M codes are machine manufacturer specific. That's why even though it might be the same control you need different M codes to accomplish the same task...

Hope it makes sense...

[DavidB]

I just thought a standard function like rigid tapping should be the same on all controllers of the same brand. That would make sence and stop us programmers going grey

 

Like G81 is the same on all fanuc controllers so why cant G84 or another G code for rigid tapping common to all Fanuc controllers?

[pip]

Our makino A55 with fanuc pro 3 is G84.2 for rigid tapping. Just throwing another spanner in the works.

[Psychomill]

I've used M29 and M135 on Makino (depending on age). M29 works for most Fanucs... but then again theres also M109 (Niigata), M105, .....all Fanuc controls.

Its 'generally accepted' but not necessarily. There are some G codes specific to machines as well even though the controls are the "same"....
