These parameters are used to specify the spindle direction, feed units and the speed range codes that are required by the machine. The Feeds and Speeds dialog is displayed.
You can specify the following parameters:
Feed max and Feed min are the feed rate limits when specified in Feed Per Minute.
Degrees/Minute Max and Degrees/Minute MIN are the feed rate limits when specified in degrees per minute.
Post supports IPR/MMPR feed units for milling - shows whether the post has been configured to support IPR/MMPR. It is deselected by default. You must select this option if you have inserted the <F-UNITS> reserved word in all milling sections of the post.
Range 1- Range 4 - are for lathes that have speed ranges. For each range, enter the M-codes for selecting the range and the maximum speed for the range.
UPM (Units per Minute) and UPR (Units per Revolution) describe the feed rate in terms of UPM or UPR (or the spindle). Only one option at a time is used by Post, depending upon FeatureCAM's segment data.
Spindle CW (clockwise) and Spindle CCW (counter-clockwise) describe the spindle On and direction code. Both of these selections use the string reserved word <SPINDLE> to specify spindle On and direction.
When CSS is enabled in FeatureCAM, the spindle speed is limited to the maximum set for the range set here.
