RIGID TAPPING

[Threept82]

Hi Guys.

I need to add a rigid tapping section to a post.

I think it needs to be done in custom cycles but

I've no idea how to go about it.

My code needs to look like this.

 

M109S???M3

G84G98................

 

But it needs to be on line above G84 line.

What post are you using and does the machine like a M5 or M3 before the call of a tapping cycle? Do you want ot do away with the tapping cycle already supprted by your post or add to the cycle you have in the post? have set all of our machines up with the rigid tapping cycle and our fanuc's with peck tapping. I have also add compression tapping to our Fadal post since one of the machines only supports that verse having a seperate post to support only that machine. If you want an M5 not calling an M3 at the beginning of the operation that is easily done with the MPMASTER post with some modifications.

Im using a modified MPMASTER post.

M3 before the cycle call on same line as the M109

code. I'm looking to add an aditional tapping call out (Rigid). Most of time I Tap using

a standard tapping head but in this case I can't

find a head that will fit the tap. So Im going

mill chuck and rigid.

You can set up your Mics. drill cycle to do it then all you have to do is call it up when you need it.

pmisc1 # Canned Misc #1 Cycle (User Option)

pdrillref

n, "M5", e

n, "M109", *ss

n, drillref, *sgdrill, *x, *y, *depth, *refht, *frplunge

 

if you make Mics 1 drill cycle Rigid tap

In Mpmaster:

 

use_pitch : 1

 

code:

---

ptap            #Canned Tap Cycle

pdrlcommonb

#RH/LH based on spindle direction

if use_pitch, pbld, n, "M109", *speed, *speed, *spindle, pgear, e

if use_pitch = 0,

[

pcan1, pbld, n, *sgdrlref, *sgdrill, pdrlxy, pfzout, pcout,

prdrlout, *feed, strcantext, e

]

else,

[

if met_tool, pitch = n_tap_thds # Tap pitch (mm per thread)

else, pitch = 1/n_tap_thds # Tap pitch (inches per thread)

pcan1, pbld, n, *sgdrlref, *sgdrill, pdrlxy, pfzout, pcout,

prdrlout, *pitch, !feed, strcantext, e

]

pcom_movea

tapflg = 1

Thanks Kyle

I changed pmisc1 to what you have and I get the following error message.

 

 

Combined Mill and Lathe Post Processor Version 9.19 © Copyright 1992-2004 CNC Software, Inc.

Processing file with SPN40...

Variable not defined: pdrillref

Post line number 1858

Program execution halted due to error(s) in .pst

 

Do I need to change something else or rename something. I don’t know anything about Misc. anything unless it in the book, not even sure what

switch to use misc values, canned text or custom drill param.

3.82,

use pdrlcommonb instead of pdrillref.

 

see Dave's code block sample above.

same error. I dont understand what to do after I change .pst file, how to implement the change when

needed.

[Threept82]

Steve does S4A have any books that covers in detail misc. values, custom drill values and

any other none standard materials. I will

send someone to S4A to pick it up today.

Did you get this resovled. The adding of soemthing to the post needs to have a little thought. I added a custom drill cycle 13 for compression tapping to a post that already uses the tapping cycle for rigid tapping. I was thinking you were trying to acheive the same task. I would copy the tapping cycle and paste it in the drilling cycle you want to use it in. Then just modify it to your liking this is much safer then trying to modify a drilling cycle to work the way you want. If you need more help put on the drilling cycle you are trying to modify and we will see if you can get you over the hump.

Thanks Ron.

I copied the tapping section into the

custom drilling 9 section and changed it

to my liking. It works fine as long as only one hole is done if more than one hole is tapped it codes as follows

 

N100T1M106

G0G90G54X0.Y0.B0S534M3

G43Z2.H#511M8

M109S534M3

G84G98Z-.5R.1F41.14

G0G90X-2.8104Y1.1851

M98P0000

G0G90X1.0384Y1.3995

M98P0000

M5

G91G28Z0M19M9

M98P9110(BTD)

G28Y0

 

I have no idea why it throws in the G0G90

or where the sub call up is coming from.

Copy what you have from pdrlcst into pdrlcst_2. You will then be able to tap multiple holes.
