Fellas I got a job here that requires turning a parabolic face on an acrylic cylinder. I rough the shape on the mill then transfer to an asg machine for finish diamond turning. Right now a NURBS spline is the geometry that drives the tool and it outputs nc as G1 moves. I have the linearization tolerance as small as it will go (.00005). This works and makes a good part but my boss thinks the spline can be converted to arcs and the nc output changed from linear G1 moves to G02/03 arcs. Can this be done and how?

Yep Mike that's exactly how we have it setup, rotating around Z axis. Sorry no pics or files as per the boss' mandate.

I tried that and it doesn't work as part does not rotate. There will be 8 different finish operations, 1 for each face.

Hi guys I could really use some help with this project. I have an 8 sided polygon - picture an octagon puck with one side at an unequal angle but also each face is not vertical instead sloped at a different angle. The boss wants to try a different way of machining this part. We have the 4th axis on our HAAS on its back just like an old fashioned rotary table. The idea is to rough the polygon using a waterline tool path but each face is to be finished seperate. Then we want to ratate a face so it is paralell to X axis and finish surfacing it, then rotate to the next face and so on. I cannot figure out how to rotate the part. I have searched and read all 7 pages of z axis rotation and still do not understand the concept. Do I need to rotate the geometry along with c/t planes? Each face is on a seperate level, do I rotate that level's c/t plane or must I creat a new one? Using the generic HAAS 4 axis post on MX3 MU1

The boss has me working on a project where we turn an eliptical shaped lens array but the crest has a flat .012 wide by .0002 tall, increasing height by .0002 on every consecutive lens. This is in metric - very tiny stuff! We're not getting quite the shape we need. I've only been able to set linearization down to .0005. Is this as small as I can go?

rapid retract is on output is I J and it's on every G2/3 line tried the post on this site before and it the machine wouldn't even load the program

I've got a Proto_AGE3 post that I cannot get to work right. It will drill fine but not mill. In both AGE2 and AGE3 I get data error 5014 the mill or pocket event is a point. Also in AGE3 I will get data error 5503 the mill and arc event do not lie in the same plane. I'm at a loss of what to do here. I think the first error might be something to do with how arc are setup in the machine def? Right now it's setup for arcs in xy only delta start to center break at 180°. Tried changing things around here but got arc is impossable to define error. Second error I've no idea. Checked planes and they are all set to top. I've also got two posts titled MPAGE3 and Generic ProtoTrak 3X Mill neither of which work for milling either. Running X2 MR2 SP1 and machine is a 1996 Trak DPM bed mill w/ an AGE3 control.

I have tripple checked those settings and they are just as you said they should be. I'm out of ideas on what is wrong.

I've been using the generic Fanuc 3X mill post on our machines with HAAS and Meldas 520M controls. On Fri the post worked fine. Today it doesn't. I think my boss might of goofed something up over the weekend while trying to edit a post for his lathe - only he'd never admit to it. Here's my problems: Before each tool change I now get this /G91 G28 Z0. /G28 X0. Y0. /G92 X10. Y10. Z10. I get no G54 at all T and H numbers no longer match. T numbers still are consecutive but for H all I get now is H0. Out of the box this post worked fine until today. I know how to open the post but I don't know how to edit things so they will work like they did before.
