Mitsubishi tapping codes...

[Thee Dragracer1951]

I got this Akira Seiki with a meldas 64 control. Does this thing just do a regular G84 for rigid tapping? or do I gotta do sumpin like Fanuc does with the M29?

Anyone got a sample of some code?

Hi Jim.We have 2 Akira here,I Just used regular G84 for rigid tap.But the feed calculated by pitch instead by revolution then.(Ex: 1/4 -20 tap

G98 G84 Z-.75 R.2 F.05).Another thing is this control is not to good,be careful with the edit mode when you want to edit your program,if made mistake you can not press cancell.It will enter what you put on (not like Fanuc or Hass..)instead cancelled them,or If lenght of the line longger than screen limited,it will jump down from another line without EOB. By the way what is the size of machine?

Thank you Sir, it's a 4020

Most Mitsubishi Controls require ",R1" at the end of the line to designate Rigid Tapping mode and the RPM called out also. The Feed is usually listed as E (but not always) and if you don't output a M3 after the tool change, the spindle is able to retain its orientation so that you can re-tap a location deeper if you need to.

 

I have two Mitsubishi's that read it like this

 

M06 T1

G00 G90 G54 X0. Y0.

G43 H1 Z.3 M08

G99 G84 Z-.5 R.3 E20. S350 ,R1

You are welcom.

Here's what my post oputputs:

 

N120 G00 G40 G49 G80 G90 G28 Z0 T3 M06

( NO. 4-40 TAPRH TOOL - 3 DIA. OFF. - 3 LEN. - 3 DIA. - .112)

G00 G90 G54 X1. Y-.125 S1200 M03

G43 H3 Z.1 M08

G99 G84 Z-.35 R.1 F30.0 1200, R1

X5.5

G80

 

 

Now. It goes to X1.0 and Y-.125 and the spindle it turning. It gets there and the spindle turns off and it does a tap cycle with no spindle on....

What the heck???

Looks like you're missing the S before 1200 in this line;

 

G99 G84 Z-.35 R.1 F30.0 1200, R1

 

Also as Dave suggested above, when I ran Meldas controls they liked the E value.

[Thee Dragracer1951]

Thanks Rob but that was me screwing up an edit. The S value was there when I ran it.

Skip the S1200 M03 on the third line of your code, It's not neccesary. G84 uses the E40 S1200 for tapping.

[Thee Dragracer1951]

I'll give that a try in a couple of minutes

[fro_matt]

Do you have a PLC-SW page under your tool/parameters? If you do there is on option to turn on spindle-synch all the time so that you don't need to post out the ,R1. Also I use F for my tap feed rate, where F is the distance between threads.

[Thee Dragracer1951]

I'll have to go look for that...

sorry I don't have the answer but what's the manual say?

I'd try to call Akira's applications dep't
