Transform by toolplane question

We have a Mitsubishi HMC with pallet changer.

The pallet has 4 sides with 3 stations on each (12 fixtures). I have a drill toolpath that I "transform by toolplane-translate rectangular-" down x3. Then I "transform by toolplane-rotate about origin-" the "translated" toolpath x3. Then I ghost the original drill toolpath, posting only the "translate rectangular" and "rotate about origin" toolpaths. (I hope I've explained well enough). This may not be the best way but without getting into what way is better.....

 

My question is this:

I would like to put the retract plane at 2" above the part when translating down (x3), but make the retract plate 9" above the part before rotating the B axis.

 

Is there an easy way to modify the post to retract to 9", for example, before ever rotating the B axis?

 

Is this a good idea?

 

Is there an easier way?

 

Works the way it is but I would like to cut out some of the redundant rapid moves.

 

If I could improve this, the boss will be very happy biggrin.gif

Yes you can do this very easily using the point toolpath and Mastercam. Make your operations and before each index use the point toolpath. So you will set-up the transform operation to rotate you will rotate the transform move operation and a point operation using operation order so it will then do the operations for drilling at the 2" clearance yet it will then move to the 9" before each index.

Here is posted code doing what I am talking about unedited right out of Mastercam.

Worked!

But man I'm not sure if it is worth all my time...

It'll take me some time to fix all the programs.

±10 minutes x 3-6 operations x 8-10 programs = alot of time

The programs aren't broke, they work fine now...

Point toolpaths worked great. but is there an easier way? less time consuming?.... modify post somehow??

Crash averted. This method of retracting the spindle works very well. But you have to be sure the program is reviewed THOROUGHLY and nothing is overlooked (programming 101). I had the tool plane and construction plane wrong for 1 of the (20+) retract points..CRASH!!!

 

Just wanted to pass along my findings.

 

Like I stated before I am open to any other ideas. smile.gif

There was something in MPMASTER that would send the Z home at each index no matter what.

 

Yes Robert I would do that if it would clear. It really depends on the machine and other things, but I have no problem moving Z in while the pallet indexes if I have .1 of clearance doing so. You should see the guy here crap bricks when I rapid to with .01 on 15" chuck spinning at 1200 rpm. eek.gifeek.gifeek.gif They all think I am crazy, but if you have a .001 of clearance you got a mile in my book. Besides I approach it like Nascar rubbing is machining. biggrin.gifbiggrin.gifbiggrin.gif

I am of the same school Ron, but if I did that, we would not ship anything. Unfortunately, Salem is not like Socal. We get our best guys from Walmart, and our lesser guys from ?????

We don't even let them set fixture offsets. We probe, preset, and do everything we can to avoid an operator from doing more than blink.

No pressure on our programmers...... rolleyes.gif

Well I do it all here so I have all the pressure to carry all on my own. What fun. rolleyes.gifrolleyes.gif

 

ckwhite does the post output max and min z moves or have anything about it in the post?? If it does it is a mpmaster detritive if it does not then it was probably based of of mpfan.

 

Here is the section that should do it from mpfan.

 

code:
pretract        #End of tool path, toolchange

sav_absinc = absinc$

absinc$ = one

sav_coolant = coolant$

coolant$ = zero

#cc_pos is reset in the toolchange here

cc_pos$ = zero

gcode$ = zero

pbld, n$, sccomp, *sm05, psub_end_mny, e$

pbld, n$, sgabsinc, sgcode, *sg28ref, "Z0.", scoolant, e$

pbld, n$, *sg28ref, "X0.", "Y0.", protretinc, e$

absinc$ = sav_absinc

coolant$ = sav_coolant

Here is what the latest MPMASTER has:

code:

pretract #End of tool path, toolchange

phsm_off

sav_absinc = absinc$

absinc$ = one

sav_coolant = coolant$

coolant$ = zero

 

# if nextop$ = 1003, #Uncomment this line to leave coolant on until eof unless

# [ # explicitely turned off through a canned text edit

if all_cool_off,

[

#all coolant off with a single off code here

if coolant_on, pbld, n$, *sall_cool_off, e$

coolant_on = zero

]

else,

[

local_int = zero

coolantx = zero

while local_int < 20,

[

coolantx = and(2^local_int, coolant_on)

local_int = local_int + one

Notice the reference plane on the first is Z9.

This allows clearance for the B axis to index.

The reference plane on the second is Z3. then moves to a safe location to allow the B axis to rotate.
