Misc. Values - Integer/Real

[CNCGUY]

How do I use a misc. value in an operation other than the first, to trigger/post something at the beginning of the program?

[Guest]

What are you trying to use it for?

This is the formatting for their usage

code:

---

fmt T 2 uptol

fmt U 2 lowtol

fmt C 2 retract

---

Here's how I define them for a probing cycle

code:

---

uptol = mr1$   #UPPER TOLERANCE LIMIT                   #### MISC REALS mr1 and mr2  ARE USED

lowtol = mr2$ #LOWER TOLERANCE LIMIT #### TO SET THE UPPER AND LOWER TOLERANCES

retract = mr10$

---

Place the variable where you need the output in the post and enter the value in your misc int

 

Then I call it out like this

 

code:

---

pdrlcommonb                                              ###FIND OUTSIDE X CENTER PROBE CYCLE ADDED 08/01/05 - JMP

#~drillcyc, e

if drillcyc$ = 14,

[

"(FIND X CENTER OUTSIDE)", e$

"(AUTO CENTERING CYCLE)", e$

"(ON THE X AXIS)", e$

pbld, n$, "G65 P8006",*drl_prm1$, *drl_prm2$, *retract, "D0.", *drl_prm3$, *drl_prm6$, *uptol, *lowtol, "V0.", *drl_prm7$, *drl_prm8$, *drl_prm10$, e$

pbld, "G04 P100", e$

To simplify what I need. . . . .

 

If any operation, other than the first, has mi10 = 1, I need to put that as a comment in at the beginning of the program.

 

code:

---

lsof

if mi10=1, "(MI10 = 1)", e

---

The problem is that this only reads the first op. How do I read all ops then post it in lsof ??????

 

Hope that explains it better

[Guest]

The problem you are going to have I think, is that the lsof is only read at the start. I don't think the posting process goes back to it.

jmparis,

 

You got it. Thats what I'm fighting!!!

 

Hopefully theres some way to get around it.

[Christian Raebild]

Yes, there is a way around that. You need to check the value if mi1 in the preparatory postblock pwrtt. You do that like this:

 

Set the variable tooltable to 1 or 3 (don't change it if it is already 1 or 3) to enable the preparatory postblocks.

 

Declare and initialize a flag to hold whether mi1 was set in an operation:

 

code:

---

mi1_used : 1

---

Then you check the value of mi1 in pwrtt:

 

code:

---

pwrtt

if mi1 >= 0, mi1_used = 1

---

Last, you check the value of mi1_used in lsof:

 

code:

---

losf

if mi1_used, "(MI1 = 1)", e

---

I hope that helps.

Christian,

 

It will take some time to absord that and give it a try.

 

Thank you!!

[CNCGUY]

Got a few hang up's to work through. For the most part I got it.

 

Thank you

Your post may not have a pwrtt post section so you may have to create it. Basically pwrtt looks thru the post first to gather information for lists at the start of the file.

 

I use this in my posts fo create a tool list at the start. This loops around and counts the tools ans numbers the operations. It then creates a list with the tools they use.

 

pwrtt # Tool table at start of file

tnote = t

toffnote = tloffno

tlngnote = tlngno

opcnt = tcnt + 1 # operation counter = tool counter +1

if t >= 0,

[

"(", "OP", 35, *opcnt , " IS ", *tnote, " -",*tldia, " - ", "OPERATION IS ", *sopcode,")", e

"( ", *toffnote, " -",*tlngnote, ")", e

"( ", "TOOL TYPE = ", pstrtool, ")", e

tcnt = tcnt + 1

]

[CNCGUY]

Mike,

 

Its in there. But you bring up something else I want to do. Numbering operations so they coincide with tool number and number of times it is used.

 

This is what I have now

First time for tool 3

N3

T303

 

Second time for tool 3

N3

T303

 

This is what I want

First time for tool 3

N31

T303

 

Second time for tool 3

N32

T303

 

etc., etc.

 

Ive been putting this of for a while!!!

You might be able to do this in the ptlchg0 section. This is for null tool changes. In english that means "what to do between operations when your using the same tool again". So you contour the outside and the cut a pocket. In between the post looks at ptlchg0 to see hoe to handel the "In-Between Cuts" part of the program.

 

In there you can create a counter for the tool and add to it. tnum = (tnum * 10 ) + 1. So you should probably set tnum = to t just after the toolchange (in ptlchg) to tnum = t.

Troy,

 

To do you your special sequence numbering at each toolchange you need to know..

1> If the tool# has already been used.

2> If so, how many times has it been used.

 

For that part of the solution, take a look at the ToolTracking.DOC on the fourm ftp site in the '/Mastercam_forum/Text_&_post_files_&_misc/' folder.

Roger,

 

Thank you. I will print that and attempt to make it work.
