v8 nci arc filter

[amd]

when running suface paraller machinning

at 0 or 90 deg 0.02 toler surface finish have alot of scracth line when on arc filter

but surface contour is ok because tool

nose only cutting when using pareller

but if not filter is very nice.

A couple of quick points here:

1. Make sure that your surface toolpath "Cut tolerance" is tighter (smaller number) than your "Filter Tolerance". The "scratch lines" you mention point towards a tolerance issue.

2. Ensure that your machine can hold the feedrates that you have selected for the toolpath. Feedrate problems won't tend to produce the "scratch lines" you mention, but will produce oversized and/or undersized areas.

The V8 help documentation for the High Feed product lists an arc feedrate test method:

--------------------------------------------

Machine a circle inside a block of expendable material such as wood or foam. Use a low feed rate to ensure accuracy. Machine the same circle repeatedly at higher feed rates until you can hear the tool gouging the material. The gouging noise indicates that the machine’s servo lag is out of range due to excessive force, caused indirectly by an excessive feed rate. This test should give you a good idea of the highest feed rate that can be used at the circle’s radius without resulting in excessive servo lag.
