This tab controls the roughing and finishing of milled features with a draft angle or bottom radius.
Side Roughing
Auto automates the roughing of features with a bottom radius or a draft angle. FeatureCAM automatically chooses tools, and number of steps to manufacture the part. If you want specific control, turn off the Auto check box and the other fields become active.
Flat-endmill, when checked, creates a draft flat operation which will rough the bottom radius and possibly the walls with a flat-end mill. Enter a number of Steps to use (in the Z direction) or leave the Steps field blank to use the Draft flat scallop height milling attribute on the operation to control the number of steps.
Radius-mill, when checked, creates a draft radius operation which will rough the bottom radius and possibly the walls with a ball-end or bull nose mill. Enter a number of Steps to use (in the Z direction) or leave the Steps field blank to use the Draft radius scallop height milling attribute on the operation to control the number of steps.
Tapered mill is only available for tapered features. When Tapered mill is checked, a draft taper operation is created which will rough the walls with a tapered endmill. Enter a number of Steps to use (in the Z direction).
If the Bottom up checkbox is checked, the bottom radius or tapered region is roughed from the bottom up, otherwise the roughing is performed from the top down.
Side Finish
These settings affect how FeatureCAM performs finishing of a draft angle feature including bottom radius features.
Automatic, when set, FeatureCAM decides how to finish the side wall and/or bottom radius of the feature.
Radius mill creates a Finish pass operation that finishes the wall and bottom radius with a radius tool. This could be either a bull nose or ball end tool. The Radius tool scallop height attribute controls the scallop height of the Finish pass operation.
Tapered mill creates a Finish taper operation that finishes the side wall up to the bottom radius, if any, with a tapered mill that matches the features defined taper. If no tool matches the draft angle, an error message is generated to warn you of that fact.
If the Bottom up checkbox is checked the walls are finished starting at the bottom of the feature. If uncheck, then the finishing starts at the top of the feature.
