I just bought the NFS Wizard.
Looks very good!

When using the circular pocket, you can specify a ramp angle and a ramp dist.
I can not find information about how to interpret these parameters.

How is the ramp angle defined? In degrees? And 0 means vertical down (no ramp)?
And what is ramp dist.? Is that ramp distance? Why do I need a ramp Distance when already a angle define?

The ramp code was written by Brian a long time ago, and I admit I have never exactly understood it. The angle is the important value, zero means straight plunge into the work. A value up to 90 is allowed, but it seems to me at 90 it would never get down. Although the ramp dist is an input the code calculates a new ramp distance value based on the tool dia and the ramp angle, so I dont think the value in the DRO really matters.

Sorry I have not got a better answer.

THe ramp angle is in degrees of slope I believe and it is used to ramp into the material instead of a straight plunge

The ramp distance is in units of length and is used to set the length of the "leadout" arc. THat part DOES NOT WORK it never changes.

IF you want to see how that part is suppose to works load up the free Circlular pocket wizard by Brian. IT works correctly there.

Ron you might take a look to see what is broke by comparing the two wizards.

GOOD news is there is a manual for the NFW package(;-)

Just a thought (;-) TP
