how to control toolpath using surface milling (projected toolpath mode)_HELP

Hello ProE CAM users....

I´m currently working on creating the finishing sequence to machine the cavity of a mold for a part that includes a dome (see image).

I know the ideal toolpath for this geometry is a spiral, however my boss has asked me specifically to generate a spiral sequence in which the tool moves from the perimeter towards the center.

So far the only way I have found of meeting his request is by using a profile sequence, moving from the perimeter to the center (and bottom) of the cavity. Unfortunately using this type of sequence I do not have control over the step over of the tool directly over the surface, I can only control the step-depth, which is measured perpendicular to the retract plane.

In order to have control over the step over parameter I used two different types of surface milling methods.

1. Projected cuts: it does generate a spiral, but it moves from the center to the perimeter (and I need the opposite)...how can I change this??

2. Cut lines: it does generate a spiral, but it is not efficient, since it begins milling a a certain depth, and alternates the depth above and below this level until the whole surface is covered.

any thoughts are appreciated, thanks

Al.

In projected cut, got to build cut, entry point and hit next. When the yellow point is on the upper edge, say accept. It will spiral in from the outside.

Alvaro,

Couldn't you use the Wall_Scallop_hgt parameter to control your step over in a profile seq?
