MPMASTER post out H1 workoffset

[cappy]

Hello,

 

I have begun the long road to tweaking my post.

I am using MPMASTER.pst with a Milacron 950 Aramatic Control on 630 Maxim. I understand the tool plane check box with work offset set 0-g54 1 g55 etc. How do I get it to H1 format. I have seen something in the post called:

 

pwcs #G54+ coordinate setting at toolchange

if wcstype = two | wcstype > three,

[

sav_frc_wcs = force_wcs

if sub_level$ > zero, force_wcs = zero

if sav_mi9 = 1, workofs$ = sav_workofs

if workofs$ < 0, workofs$ = 0

if workofs$ <> prv_workofs$ | (force_wcs & toolchng) | sof,

[

if workofs$ < 6,

[

g_wcs = workofs$ + 54

*g_wcs

]

else,

[

p_wcs = workofs$ - five

"G54.1", *p_wcs

]

]

force_wcs = sav_frc_wcs

!workofs$

]

 

I have seen other posts with H values.

 

Please help.

 

thanks,

Greg.

What do you need your Work Offset callout to look like?

 

or is that H1 a Tool length offset?

[Storkman]

Might be easier to use the Fadal post and make the E1 into H1

John,

 

The H1 is a work offset. We have 16 per pallet.

I know H's can also be used for a tool length offset as in a Fanuc 18M series.

 

Basically we mill on B0, B90, B180, B270.

The work offsets are H1-B90, H2-B270, H3-B0, AND H4-B180. I don't think we have used anymore than four.

 

Thanks,

Greg.

So it is a pallet index?

Terry,

 

The MAXIM has a AWC automatic work changer. ^ pallets shuttle. I am not sure what you mean by pallet index. We do not index or shuttle a new pallet in the machine during a part program. Once the "1st operation" is done. The pallet is sent out and the "2nd pallet operation" is performed. Regardless of what pallet is in the machine the B - side face will have it's own workoffset H value as mentioned above. If I work on B90 the work offset coded is H1.

John,

 

The sample below is what our old APT was doing.

Notice the H1 value in the long line of code.

Couple of ways to do this...

 

if wcstype = two | wcstype > three,

[

sav_frc_wcs = force_wcs

if sub_level$ > zero, force_wcs = zero

if sav_mi9 = 1, workofs$ = sav_workofs

if workofs$ < 0, workofs$ = 0

if workofs$ <> prv_workofs$ | (force_wcs & toolchng) | sof,

[

g_wcs = workofs$ (or + 1 if you want a work offset of 0 to equal H1)

*g_wcs

]

force_wcs = sav_frc_wcs

!workofs$

]

 

At the top of the file change this:

fmt G 4 g_wcs #WCS G address

to this:

fmt H 4 g_wcs #WCS G address

 

With this you still need to select your work offset in mastercam as you were before, it's not tied to the angles.

Chris,

 

thanks!! I will try that and let you know how it worked.
