Utility: Multiaxis Machining
Introduction
This topic will explain the options found in the Utility tab of the Multiaxis Machining operation.
The Utility tab
To learn about Utility parameters available in other operations, view the Utility Tab.
The Utility tab is only available for the Multiaxis Roughing Pattern and allows you to adjust the feed rates in various situations and the max angle step for rotation axis.
Feed Rate Control
- Radial chip thinning feed control
With this check box cleared a zone cannot be selected to have feeds handled differently inside of it.
Select the check box to turn on the feed control zone option which allows you to specify a geometric boundary as an area to apply a special feedrate. To define the parameters in the Feed Control Zone dialog box, after selecting the check box, click 
.
Radial chip thinning feed control
-
Min. feed rate (%feed rate) - define the minimum percentage of the feedrate to be used when adjusting the feed for radial chip thinning.
-
Max. feed rate (%feed rate) - define the maximum percentage of the feedrate to be used when adjusting the feed for radial chip thinning.
- Feed control zone
With this check box cleared a zone cannot be selected to have feeds handled differently inside of it. Select the check box to turn on the feed control zone option which allows you to specify a geometric boundary as an area to apply a special feedrate. To define the parameters in the Feed Control Zone dialog box, after selecting the check box, click .
Feed control zone
-
Geometry- click
to select geometry as the boundary area for feedrate control.
-
Offset- type a positive value here to offset the boundary area from the selected geometry thus making the feed control zone smaller.
-
Inside feedrate % - type a percentage of the feedrate that is applied inside of the feed control zone.
-
Outside feedrate - type a percentage of the feedrate that is applied outside of the feed control zone.
- Use rapid feedrate
Select the check box to use rapid feedrate and type the desired rapid feedrate value in the box. Clear the check box to turn off rapid feedrate. Retract moves, for example, now use the standard feedrate.
Feedrate for Direct/Spline Links
-
Area Links
Select the check box to define a feedrate value used for direct or spline links. Clear the check box to use the program feed rates. -
Links Between Slice
Select the check box to define a feedrate value used for direct or spline links. Clear the check box to use the program feed rates. -
Links Between Regions
Select the check box to define a feedrate value used for direct or spline links. Clear the check box to use the program feed rates.
Miscellaneous
This option determines the maximum angle step, or amount or rotation, applied to rotation axis movements between toolpath points. Select the check box to turn on the option and then type the angle value in the box. Any machine movement beyond this angle is reduced by adding more toolpath points to smoothen the machine movements as a division of the angle change and maximum angle step. This is provided to reduce or eliminate abrupt machine movements, specifically for some machine controllers that do not limit large rotation changes, which can break tools or gouge surfaces.
