WORKING SURFACE MASTERCAM TO XILOG

[OhadAdar]

i am using Mastercam to create code for routing complex surfaces with morbidelli author evo.
every thing is working fine but i have a problem.
mastercam post provides a program with many small G1 lines (1-3mm length movment) and the machine acclerate and stops each line. the result is that the machine is shaking, the work time is extremly slow, and the result isn't as it should be.

is there a way to adjust the slowdown and the accleration speeds for these kind of jobs? the V speed was set to max 20 M/min but the acctual time was maybe 2 m/min.

please advise

Hi

I work the same way as you, programming in MasterCam, post to Xilog and then routing with SCM Tech Z30 that has Kvara controller. (Moldmaking) Do yours machine has kvara or NUM?

Like you I also has problem with the machine shaking. I usually run a filter in MasterCam so it create's G2/G3 where possible, it's getting better but not quite ok.
Lately I also have problems with the machine does not follow my G2/G3 code as it should...(Are going to start a thread about that)

In Xilog there is something called "jerk" that I think affects how the machine reads the code, if you set the value right the machine should "float" properly.
BUT I had a technician from the company that sold the machine to me in my workshop a few days and he created a program in Alphacam which we tested to run but the machine shake lot. So he began to adjust the "jerk" but after many test he give up and adjust the lenght movment from 1mm to 10mm... The result of that was the mold was more angular then round..and the machine still shake

In MasterCam can you also set "highfeed" which adjust the feed so the machine "float" better. I've never tried it myself but I know works very well on other machines.
What version of MasterCam do you use?

Maybe not so much to help butter maybe something.

Sorry for my bad english!

Dear Magnus
for your question : i use MC X4 mu3 and i am in the process of upgrading to X5 in the next weeks.
Xilog Plus 1.13 with Num control

from my experience the MC X4 filter work nicely when using surface finish contour and flowline. all other spiral, highspeed, radial etc. are providing G1 code without G2/3. the result is a very long code and poor machining result.

last week i have talked with SCM group several times. we made adjustment using JERK function with no use.
you can try typing in text mode in xilog
SET JERK=60 or = 90 or 260 or any other parameter they asked me to try and all came up short. Just no good. like u said the service of scm gave up on the jerk function.
another test was made by one of the xilog proffesional of scm and advise me to add the parameter in iso code
ISO ="%B100"
still no result the machine is still shaking and cannot build up speed the way it should.

i send scm a movie of the problem and i hope to get some answers fast.

Thank you for the information!

Now that you mention it, I see that depends on that toolpath I choose. Has never thought on that before.

Maybe I'm stupid but I've never understood exactly that the jerk function do?
Do you have a good explanation?
I also wonder if you know what "ISO ="%B100"" is?

Please let me now when you get a response from SCM!

I wonder if you've heard anything new from SCM?
