Dual feeds rigid tap cycle

[tala]

Hello folks,

 

So, I've seen this before, and for the life of me cannot remember where

in the post I need to make the change...

 

Here's the output:

 

-----------------------------------

(CUT TAP 16X 8-32 HOLES)

( 8-32 TAP .164 DIA 32IPM 1024RPM)

N15M19

G0G17G40G80G90

T15M6

(MAX | Z.5)

(MIN | Z-.4658)

S1024M5

M8

G0G90G54X16.Y-1.5

G43H15Z.5T6

Z.3

G84.2G99X16.Y-1.5Z-.4658R.3F.0313S1024

X16.Y-2.F32.

X16.Y-3.

G80

Z.5 M9

G0M5

G91G28Z0.

G28Y0.

G0G91G30X0Y0Z0M19

M30

----------------------------------

 

As you can see there are two feeds, one on the G84.2 line

and the second on the very next line.

They're different values.

The correct value is the first feed of .0313

The second stops the machine.

 

Using an mpmaster post...

 

All help appreciated.

Thanks!

Your tapping cycle for the remaining holes needs to be modified. I will get on my Pc in a few and give you the exact postblock

Mine does not have a feed call in it, if yours does I would remove it. Can't think of any instance I would ever want to change feedrates in the middle of a tap cycle.

Hello,

 

This is the old code from mpmaster:

-----------------------------

ptap_2$ #Canned Tap Cycle

tap_feed = abs(speed / n_tap_thds$)

pdrlcommonb

pcan1, pbld, n$, pfxout, pfyout, pzout, pcout, prdrlout, dwell$,

tap_feed, strcantext, e$

pcom_movea

-----------------------------

 

This is the revised code:

It solves the problem...

-----------------------------

ptap_2$ #Canned Tap Cycle

tap_feed = abs(speed / n_tap_thds$)

pdrlcommonb

pcan1, pbld, n$, pfxout, pfyout, pzout, pcout, prdrlout, dwell$,

strcantext, e$

# pcan1, pbld, n$, pfxout, pfyout, pzout, pcout, prdrlout, dwell$,

# tap_feed, strcantext, e$

# previous two lines contains tap_feed which places an additional

# feed rate into the rigid tap cycle... removed Tala 5/23/12

pcom_movea

------------------------------------

 

 

Here's the correct output:

----------------------------------

T15M6

(MAX | Z.5)

(MIN | Z-.7188)

S1024M5

X8.7957Y-4.6268

----------------------------

 

Notice,only a single feed rate...

 

Thanks!!!!!!!!!!!!

which variables... Thanks for the help, Much appreciated!
