Does anyone have some recommendations for a computer to run Vericut FAST? Will still need to be able to run MasterCam and Catia. Has anyone run Windoze XP 64 with this combo? And will huge amounts of RAM help?
-
I guess we're going to talk to Austin NC and see what they can do for us. Maybe be able to turn it off and on and adjust tolerances on the run.
-
I have seen the switch, but where are the tolerances set? Whatever cimpro is doing now is too coarse of steps, that is why I was hoping to use mastercam.
-
I am using a CimPRO post processor.
-
Turning off support for arcs does not do what I need. It leaves arcs in the nci file and tells the post to break them up but I am not using a MasterCam post.
-
Arc Filtering off does not affect corners already programmed arcs.
-
We have a new high speed machine that apparently runs smoother and more accurately when programmed with lots of point-to-point data (lines) instead of arcs (has something to do with the way the look ahead handles arcs). Is there a way I can force MasterCam to always output arcs as point data? The deviation tolerance would need to be .0001". We are using a third party post so the point data needs to be in the .nci file.

Small beginner projects could be cut in wood, especially if you keep the grain vertical and walls thick. Hard types of wood might machine better than pine and still be cheaper and safer than aluminum. Wood might even be good to varnish and be pretty. Have the kids start with a chunk of old hedge fence post or piece of maple firewood, look for twisted grain or crotches. I have made test pieces with the foam insulation from the lumber store, pink is OK, blue works better.
-
It helps if you 'lock' the angle you want before selecting the arc.
-
You are using surfaces for walls? I will try to duplicate the problem. (I rarely use surfaces, just chains.) If you are using chains for walls and the surfaces just for tip control I have not been able to duplicate your problem.
-
What kind of changes? I just did some trims with no problems.
-
Have had no problems like that. Had some issues when I tranformed swarf toolpaths but still not like your problem.

AirO2bic Mouse. Supposed to help prevent carpal tunnel.

I like the toopaths I get but is there any way to tell it to not worry about always climb milling? I would like to leave the cutter down as much as possible and rough material off both climb and conventional. At 30,000 rpm and 900 ipm the machine doesn't seem to know the difference and during the all-climb-mill toolpaths the machine literally spends more time out of the cut than in.
-
HSS Waterline supports check surfaces, where do I set how far to stay off those surfaces?
-
Thanks Mark, I hadn't noticed. I need it and am going to try it right now.
-
Whenever I have had to cut thread reliefs it was either spelled out on the print or called out "thread relief per [MS spec]". So yes, there are some specs out there someplace but I don't recall the names. I'm not aware of any published design guidlines.
-
Try tightening up the tolerance (smaller number) in the flowline parameters.
-
I like to use the 'ramp' option with the contour toolpath for something like this. Drive on a circle and define your ramp parameters.
-
Theoretically 'R' programs would produce the same parts as 'I,J,K' programs. But because the control has to compute the actual path and it starts with different data in each case differences can occur (due to rounding errors). Check your machine's manufacturer for which method is recommended.

Feed for drills are usually called out in Feed per Revolution (IPR), this is NOT the same as Feed per Tooth (IPT). We usually call them both 'chip load' but for drills the number of flutes is already factored in and does not apply to the equation. 1700rmp x .012ipr = 20.4ipm For end mills one does need to factor the number of teeth into the equation. 4000rpm x .0026ipt x 2teeth = 20.8ipm

Hmm, I thought the old thing of changing colors when Zs matched was an evil bug because it hid which tool actually cut a floor. I am very glad it went away.
-
If you have rigid tapping capability do not use floating tapping holders unless you are tapping into pre-existing holes. If you are willing to pay for the quality, go with Emuge, tell you rep what your application is then use the recommended tap with their recommended speeds.
-
No, what I see does not seem to be related to duplicate geometry on another layer.
-
At this point anyway 'combine views' has no effect. Maybe I needed to do it before mirroring the part? Too late now for that. Has anyone besides myself seen what I described?
