ADDING A START AND END POINT IN POST

[VelocityMach]

I am running a mori seiki lathe using mastercam x5. I'm not sure what the original version is but I'd like to put a start and end rapid point in at the beginning and end of the toolpath so i can clear my tailstock. I have tried every combination of possiblities that i know of. I'd like a normal face cycle to look like this:

 

(ROUGH FACE)

G54

N1 T0606

G99

M46

G97 S223 M03

G0 X20. Z4. *******

G0 X3.4272 Z.0807 M8

G50 S3600

G96 S200

G1 X3.2857 Z.01 F.01

X-.2468

Z.11

G0 Z.16

G0 X20. Z4.*****

M9

G28 U0. W0.

M05

M01

 

Is this possible?

Have you tried a reference point? Have you tried a point tool path?

[VelocityMach]

yes, and yes. both work to some extent. I'd rather not have to program a rapid point everytime i use this machine. The post is only used for the one machine and the machine runs a variety of the same parts. so the best way i can see is just add it to the post. I pretty much need it going there for every tool.

In the machine def, click the axis combo icon at the top. In the window that pops up you will see "reference points" at the lower left corner. I believe if you enter them there it will give you what you need.

[VelocityMach]

That seems to work about half the time. I just changes it and it works for my live tooling operations not the turnings ops though

[K2csq7]

Do you have more than 1 axis combo? You would have to do that to each axis combo. Click the axis combo then click the ref points thing.

Just changed all 4. same results. I take its not possible to add those locations to the post?

Not impossible by any means.

How do you want to do it? hardcode so it's always there? tied to a misc integer?

Do you know how to use the post debugger?

 

 

It may be easier to draw a point when you start a file, then after you chain whatever your going to cut, just chain that point before green checking out of the chaining dialogue box.

This is up to you to decide.

[VelocityMach]

I guess either hardcode or if you can explain tied to misc integer that may be an option. I need it for every toolpath so i'd rather not have to draw points. I do not know how to use the post debugger, in fact never heard of it.

[VelocityMach]

I think I figured something out. Thanks for your time.

[K2csq7]

What did you figure out?

 

As for using misc integers... it doesn't get much easier, search for stuff on the forum, make a backup of your post so you can try things without fear of losing everything!!

 

if mi6$ = 1, 
   [
   pbld, n$, "misc int 6 is on", e$
   ]
   else, 
  	[
  	pbld, n$, "misc int 6 is off", e$
       ]

Sorry, didnt see you had added anything else. When you program a lathe toolpath it asks for a point OR where to start the contour. If you select the point, contour, and point again it seems to work great.

 

Again sorry for the delayed reaction, thanks for the help.
