So methods is saying thermal comp won't help me because my dimensions are within a small area. Isn't thermal displacement calculated from home of the ball screw? So if "y" center of rotation is approx -8.00" from machine home. Wouldn't thermal comp help me?
-
I'm trying to hold a +.05mm -0.00 tolerance on a feature that's milled at c0. and c180. The feature cut at c180. is out by 2x the error in Y. The machines are only running 1.5 shifts and i have been spending half a shift chasing my tail before I get any consistency. Material is approx 500/ft Pulling out my hair!!
-
What do you mean by cheating? Chasing offsets?
-
Anyone doing tight tolerances on robodrills? I'm having a heck of a time chasing these features around. It's on a brand new robodrill with a koma 5th axis table. I looked into the thermal comp but it has to be "taught" from what I understand... Thoughts?
-
Nope. There's a bug. I've used it on other toolpaths with no problems
-
R u doing a drill cycle?
-
It's not that bad. Just make sure your coolant is flushing well
-
What are the drills at the edges for?
-
Heres one i use on our plastics machine. Mill the small cube by face milling front, back, left and right. Mill the big cube by contouring at top view. TEST PART.MCX-7
-
You can use solid edges for chaining. Just pick solids and partial loop. Its a little different than standard chaining but it works for simple stuff.
-
If you want I'll send u a file of the test part that I use

L133 and 135 control x and z at b90. Mazak has a spreadsheet that "calculates" these numbers. It's usually not right. I clear those numbers out, run a test part. Then put an offset there after I get s5 and s12 as close as possible
-
I think it's alt+f12, then click rotational center.
-
Also clear out L133 and L135. I'm my experience, mazak only gets it about that close. Then I run a "test part" to get it nailed dead nuts
-
Are you opening it on the same system it was saved on? This sounds like the system that saved the file is on a newer release than the system used to open the file
-
I believe parameters s5 and s12. Add your shift to your g54, s5 and s12 parameters
-
I always lean to this toolpath other toolpaths don't behave like I want them to

Morph between two curves

Ok now I can get in just fine but every few minutes it pretty much freezes for 30sec to a minute. I'm guessing it's making sure there's still a license available... Is there a way I can make it a longer interval between these searches?
-
Nevermind i got it! Worked the first time! Thanks alot Allan
-
I changed those values to 15 and now it tells me no sim found even faster than before
-
I used to open it at work, close my laptop and head home. it worked fine in X7. Now in X9 when I get home it has already kicked me out. I think I am going to get my license swapped back to a dongle
-
i think your post probably runs a macro to figure the distance from your new "zero" to your center of rotation. thats what mine does anyways... it does this so you can probe your part, then the macro calculates the distance and updates.

sign up for grabcad.com its free and theres millions of solid models on there. a nerd like me can easily spend hours on there lol!
-
Yes its a laptop. It works fine anywhere else.
