Newbie question

[Weyland]

Having read the requisite newbie admonitions,

I find I'm still wont to ask this, as I don't

think it out of the realm of politeness...

 

I'm learning MasterCAM at school, and

we're using it with a Bridgeport V2XT.

 

I've found that the BOSS10 post from an earlier Version 9 works pretty well

after importing it into X and converting it with some instructions that I've

found, but I've found two quirks that I'm trying to learn how to fix/avoid/understand.

 

The first is that the school's Bridgeport

V2XT absolutely hates it when there's no

decimal number issued to a feedrate command.

In other words, it errors out if the feedrate

is written as F20, but likes it when it is F20.0.

Is there a way to tell the post processor in X

to automatically make all feedrates decimal format?

The next one is much more important to me.

 

After generating some toolpaths, I've noticed

that the resulting post is not using G8/G9.

I dealt with that for a little while by hand

editting them in, but have now created a program

that is 5000 lines and would hate to have to do

this continually as my learning curve progresses...

 

Is there a way to edit the post processor

or otherwise tell X to use the G8/G9 commands?

 

Thanks for your time,

Welcome to the forum!!!! Glad to see you step in here, it really is a great place to get information to help you with any machining and Mastercam questions.

 

I'm sure the answer to both your questions is 'yes'. I can't help with X but someone here will be happy to help you soon.

 

Good luck!!

 

BTW what the heck are you doing up at this hour?!?!?!?!?

[J Coulston]

!Back up your post first!

 

You might only need the decimal and not the trailing zero.

 

Check in your post for the following.

 

#Common format statements

fs2 15 0.2 0.1 #Decimal, absolute, 2/1 place

result F30.

 

fs2 15 0.2 0.1t #Decimal, absolute, 2/1 place

result 30.00

 

Beaware that every variable that uses fs2 15 will be affected by the formating change. You can add an additional ones if needed.

 

# Toolchange / NC output Variable Formats

fmt F 15 feed #Feedrate

 

The 15 is calling the formating from the format statment fs2 15.

 

Do you mean M08 coolant on and M09 coolant off?

Hi guys,

 

BernieT - Thanks for the welcome.

I'm up because I was googling for answers

and because I'm taking care of my wife as

she battles lung cancer. Basically, my life

has no actual sleep schedule these days,

so I try and stay productive when I can.

 

John - Thanks for the tip on the formatting~!

I'll try that when I go back in to

school and let you know how it turned out.

 

As for the codes - no, I mean G8 and G9.

Axis acceleration and deceleration off and on.

Otherwise known as "continuous contouring"

or "high speed machining" in some circles.

 

Basically, it allows the machine to

*continuously* move from one commanded

move to another, without pausing when

reaching the end of the first commanded move.

 

Thanks,

 

Weyland

Hey John,

 

I had brought the post home with me to try and

learn from, so went searching for the part you

reference, but only find the below pasted part.

 

Is this the right part, or am I missing something?

 

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

# Format Statements - i=incr, n=nonmodal, l=leave ldg, t=leave trlg, d=delta

# --------------------------------------------------------------------------

fs 1 1.4

fs 2 1.4l

fs 3 4 0

fs 4 2 0n

fs 5 3.1t

fs 6 3 0ln

fs 7 3 0n

fs 8 8 0n

 

Thanks,

 

Weyland

[Weyland]

Sorry for the barage...

 

I just found this in there but I don't know how

to decipher/interpet it to know what's going on -

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

sgaccel G08 # Axis acceleration code off

sgdecel G09 # Axis deceleration code on

sgacc

 

fstrsel sgaccel dirchg$ sgacc 2 -1# Select accel/decel code with dir. chg. flag

 

Best,

[Weyland]

I've been researching this as best

I can, and have found reference to the

MastercamX_post_parameter_ref.pdf, in this thread -

http://www.emastercam.com/ubb/ultimatebb.p...ic;f=1;t=022817 ,

but don't have a clue what I'm looking at and

haven't found any references to G8/G9 in that pdf.

 

Anyone? Bueller?

 

Thanks,

 

Weyland

[Hardmill]

Give the post monkeys (err gurus) a bit. Im sure youll get

all the answers you need.

 

And welcome to the forum

 

 

PEACE

[Weyland]

Thanks. Appreciated.

I've been trying to learn on my own, but I'm not doing so well.

I went through the workbook on Milling, and "got" that pretty well, but no one knows where the workbook for Lathe is, and I'm not "getting" that on my own *AT* *ALL*.

My teacher is being as helpful as he can be, but the school lost their MasterCAM instructor due to health issues, so I'm kinda just trying to figure it all out with trial and error.

(much more error)

 

Love those beer smileys.

 

Best,

 

Weyland

[Weyland]

Bump...

 

Is there a way to rename this

thread to better reflect my question?

Send me your post I will have a look.

[Slepydremr]

I updated the boss 10 post to X and it out puts the feed as you would like it With one number after the decimal with these setting in the post.

 

code:

---

# Format Statements - i=incr, n=nonmodal, l=leave ldg, t=leave trlg, d=delta

# --------------------------------------------------------------------------

fs 5 3.1t

---

code:

---

fmt  F 5 fr$     # Feedrate

fmt F 5 frplunge$

---

HTH

[Weyland]

Don -

 

Thank you for the offer of help.

If you find something, could you tell

me what it was so I can try and learn?

 

Slepydremr -

 

I do have those, except for "fmt F 5 frplunge$".

Should I necessarily have that?

Is it something desireable to add to the post?

 

Referencing my question about G8/G9, I'm

wondering (probably thinking too much) if it

isn't the post and rather something that we don't

know to "turn on" or enable while creating the toolpath...

 

Is there some way to tell MasterCAM to always use G8/G9?

 

Thank you for your help, guys.

 

Best,

 

Weyland

[Weyland]

Aha... I found the edit button...

[Kannon]

Dont feel bad Weyland..

Ive called Dan ROY before and he still talks to me. Sorry bout that Dan...

[Weyland]

Hahahahahaha~!

You got to it before I could edit it~!

 

*BUSTED*.

 

Cheers,

The boss 10 post I updated had that frplunge in there for the drill cycles. I'm not sure if you need to add it or not. I do not actually use this post but it was on my MR0105 CD so I thought I would check it out for you to see if I could figure out your problems. I'm sure it would be okay for me to send it to you if you wanted to try it since it was right on the CD.

 

About the G08 and G09. I see it in the post but I've never used that option so I don't know how it should look when it's working right. Could you post some code up here to show me how to try and make it look. I might have some more free time later to play with it.

[terry5357]

Is the G8/G9 modal. Is that required at the (on) beginning of tool sequence and (off) at the end of the tool sequence. If you are not sure, I would think that it needs to be turned on and off with each tool that requires it. Drill canned cycles probably don't need it. I used to program a Kitamura Horz That required the high speed machining on and off. this is also known as corner rounding. There may be a way to force it on and off with a "*" in the correct place. the post guys will and can definitely get you going on this, unfortunately you may have to wait until monday when they all come back to work.

 

Good Luck

[Weyland]

Slepydremr & Terry5357 -

 

I've been reading the manuals and

Bridgeport calls it (G8 & G9) "modal

deceleration off" and "modal deceleration on".

 

I've seen other places call it

"continuous contouring" and "high speed machining".

I guess it just depends on who you're speaking with...

 

An example of some code and its use would be the following -

I'll post some without it, and then follow it with some with it.

 

WITHOUT using it -

 

N10 G0G90G70G40G75

N20 G0 X0. Y0. T1 M6

N30 G0 Z0. S3500 M3

N40 G0 X.8032 Y2.0288

N50 G0 Z.25

N60 Z.1

N70 G1 F7.0

N80 Z-.375

N90 G3 X.897 Y1.935 I0.897 J2.0288 F25.0

N100 G1 X2.54

N110 G2 X3.6025 Y1.1612 I2.54 J0.8187

N120 X3.785 Y0. I0. J0.

N130 X3.6025 Y-1.1612 I0. J0.

N140 X2.54 Y-1.935 I2.54 J-0.8187

N150 G0 X2.995 Y-1.9375

 

WITH it -

 

N10 G0G90G70G40G75

N20 G0 X0. Y0. T1 M6

N30 G0 Z0. S3500 M3

N40 G0 X.8032 Y2.0288

N50 G0 Z.25

N60 Z.1

N70 G1 G9 F7.0

N80 Z-.375

N90 G3 X.897 Y1.935 I0.897 J2.0288 F25.0

N100 G1 X2.54

N110 G2 X3.6025 Y1.1612 I2.54 J0.8187

N120 X3.785 Y0. I0. J0.

N130 X3.6025 Y-1.1612 I0. J0.

N140 X2.54 Y-1.935 I2.54 J-0.8187

N150 G0 G8 X2.995 Y-1.9375

 

(notice N70 & N150)

From what I read, it is similar to a G99.

Basically, if you don't use it, the machine

executes a move, pauses, executes a move, pauses, etc...

When you *do* use it, it moves continuously

and smoothly throughout all the movements.

 

 

Does this make sense? Clear as mud?

Hi everyone, I hope that someone could help me in figuring out why there are no lines appearing whenever I create one. it only becomes visible whenever I click FIT. Like for example after creating a rectangular shape etc and the when I'm going to make a parallel line the line wont appear unless I click FIT. hope you get it. I'm a new user and getting the hang of it, but just this morning when I got bored and decided to work on something the line that was supposed to be there just was'nt there anymore, unless you click on FIT. hope you guys could help me, thanks much.
