MasterCam X interpolation resolution

[qnet2]

Hello again
this one is real problem i cant find a way to get a smooth cut on this chain
ive looked but cannot find the key to reducing the g1 moves to a finer res
or changing them to an arc

Thanks

My control has a built in tangency factor that i can adjust. This smooths out rough splines for me. Maybe you have something similar.

[ahunter9624]

also if you look in your operation parameters you can try using arc filtering

[qnet2]

Filtering did no real good
i guess MC just cant hack it

[ahunter9624]

have you cut one? Dont base your surface finish off the image in verify

[qnet2]

yes i cut one, however with cimco edit it's clear to see that the distance between the straight lines is way more than wanted

Your arc is not perpendicular to the tool axis, so it would be hard to fit an arc accurately

plus...arcs will not be fit to the toolpath as the "Filter Ratio" is OFF.
To get any arcs, it must be ON (one of the other selections in the pull-down)

To get closerr point to points, make the "Total tolerance" smaller ( say 0.0001"), this is the distance that Mastercam will allow the toolpath be away from the actual contour that you did select

Note!....any splines that you select tend to output as point to point...you can "Simplify" any splines ( "Edit" pull-down ) to get some arcs ( depending on your settings )

( hint....break long splines into shorter lengths to get more arcs )

Thanks guys
i'll give your hint a try Superman
