Machine simulation speed up

paehv · 2006-03-08 09:45:07

We have 10 virtual machines (3, 4 & 5 axis and Mill/Turn)
When we run a machine simulation, we see that there is a difference in
the speed of the simulation, however most machines are quit fast.
2 machines are so fast simulating 3-axis that you need the speed slider to
slow the motion down to be able to actually see the tool.

However 1 machine (5-axis) is so incredibly slow -even on 3 axis motions-
that it's pratically unusable
(21000 lines of NC code -3axis-, take about 170 minutes to simulate. With an other machine this takes 32 minutes)
:cry:

:?: What may be causing this?
:?: Which settings have such an influence on speed?
:?: How to optimize this?

I can give you a few ideas

I have seen dramatic differences in speed, depending on the complexity of the stl files I use when doing collision detection.

I have one file where the holder is a large STL model of a Tecnara 90-degree head. By large, I mean a lot of polygons. The program is internally machining a very complex model. This particular program runs only approximately 40 lines of g-code an minute. Same part, same machine, no 90 head, where the holders are not in close proximity of to part, over 500 lines a minute.

I believe that Vericut detects when components get close, and the accuracy goes way up in close proximity, comparing each polygon for collision.

(1) try turning collision detection off, and see if that effects the speed. This will tell you if it is the component models.

(2) Look at rotary tolerances. Might not be what you think.

(3) Try turning machine simulation off, (only workpeice view on)

(4) Look at cutting tolerance. that may slow you down. Try running with a simple block.

(5) make sure axes are not displayed. This puts Vericut in death mode.

(6) Sometimes the slider bar is not all the way to 100%

(in Version 6.0, the slider bar turns yellow if not at 100%)

One day, The Vericut Gods will shine on us, and there will be a number next to the slider. And you will be able to see what percent the slider is on. And even type in the exact number you want. And perhaps, be able to have a little more control there. Key in more control with a decimal: 96.7

:twisted:

Finally, for 15 years now, I have 2 computers. One for Vericut, and one for programming. Some Vericut process are fast. others take hours. I set Vericut to stop on errors and than I go back program something on my other computer.

Computer hardware is a fraction of what we programmers make, in a year. To take advantage of a smart programmer?s ability to multitask in this fashion is what I recommend to any manager.

:wink:
