Morph Advanced options


So not a Guru
 Share

Recommended Posts

We have a Mazak VCU500 5X machine that runs very choppy whenever we use the high speed smoothing control, no matter what setting we use (the settings range from M821-fastest, to M826-most accurate).

I'm wanting to try using the advanced options in the morph paths to see if we can improve this. Is anyone familiar with what the smoothing distance does? Is it rounding the corners for the distance entered?

I aware that the best option would be to have the Mazak AE to help us properly tune the parameters, but we contacted our regions office about it several years ago and couldn't get it done thru them for whatever reason.

The Smoothing Distance that you see in the Cut Pattern advanced options for Morph is applying essentially a corner rounding effect to the actual generated cut pattern to smooth out sharp changes in direction on the surface. It blends the direction change (defined by the break angle field) over the distance you enter. 

When you say choppy, what do you mean? Is it only choppy when rotary motion is added in? Does the choppiness get better or worse when you increase point density in a given path? Can you upload a path example?

Have you played around with the Maximum Angle Step field in Tool Axis Control? Some machines really don't like seeing large angle transitions and not giving them enough 'resolution' in terms of angular change points density to see a clear acceleration/deceleration path will cause choppiness. Some machines are just the opposite, in that loading them with so many points will cause the control to choke.

The solution for you could be any number of things, from machine-side adjustments to a different programming approach to get smoother code out of the gate, so getting a little more detailed on what works/what doesn't on a known example will allow us to help you.

Thanks Dylan, I'll try adjusting the maximum angle and see if that gets us any improvement.

If not, I'll upload a file.
