Multi-Axis Sweeping: Radial ParametersRadial strategy
Scallop height: Distance on part: Distance on plane: Number of paths: Stepover side Multi-Axis Sweeping: Tool Axis ParametersNote that modifications of the tool axis generated by the mode you have selected apply only to the machining passes, not to the between paths passes. (Only Tool Axis Parameters tabs containing parameters have been captured) You can define several axes with this icon:
The view and the start directions define the machining guiding plane: machining is done in planes parallel to the guiding plane. The view direction defines the accessible areas for the tool. These areas are accessible if the angle between the view direction and the normal to surface is less than 85 degrees. The tool axis definition depends on the Tool axis mode. The tool axis
arrow turns white when its definition box is not available Clicking one of the direction arrows displays its definition box.
Tool axis mode Below you will find the explanations of the various modes, then the explanations of the associated parameters.
There are several guidance modes as follows: Fixed lead and tilt:
Variable lead and fixed tilt:

The purpose of the variable modes is to avoid collisions between the part to machine and the tool. | |||
Fixed Axis![]() ![]() The tool axis remains constant for the operation. Thru a Point Normal to Line Optimized lead is not available for a barrel tool. The tool axis is allowed to vary from the specified lead angle within an
allowed range. Optimized lead works as follows:
If the required lead is outside the allowed range, the tool position will
not be kept in the tool path. C1= tool curvature along motion 4-Axis lead/lag is not available for a barrel tool. The tool axis is normal to the part surface with respect to a given lead angle in the forward direction and constrained to a specified plane. Click the 4-Axis Constraint arrow (N in the 3D window or
the arrow normal to the plane in the sensitive icon) and
set this direction in the dialog box that appears. This is the normal to the
plane in which the tool axis is constrained. Specifies a user-defined incline of the tool axis in a plane defined by the direction of motion and the normal to the part surface. The lead angle is with respect to the part surface normal. Maximum lead angle Minimum lead angle Tilt angle Allowed tilt Minimum heel distance |

Thru a guide![]() ![]() This strategy is used mainly to machine revolute surfaces, e.g. hub machining, deep pockets, ... The tool orientation is controlled by a geometrical curve (guide), that must be continuous. An open guide can be extrapolated at its extremities. Click the red curve in the sensitive icon and select a curve in the 3D viewer. The tool can be oriented From or To the guide. Mode

Lead angle Specifies an angle in the forward direction, between the default tool axis and the actual tool axis: ![]()
Note
that depending on the Lead angle, the tool axis will not remain on the
tilting guide: |

Multi-Axis Sweeping: Cutter Compensation Parameters(Double-click the part operation and push the Machine icon to open the
Machine Editor) In the Machine Editor, the Compensation tab contains options for:
If the options are set as follows, compensation can be managed at
machining operation level. Allows you to manage the generation of Cutter compensation (CUTCOM) instructions in the NC data output: The following options are proposed: 3D Contact (G29/CAT3Dxx)
None Multi-Axis Sweeping: GeometryYou can specify the following Geometry:

![]() |
Note that infinite geometries e.g. planes, selected as part or check geometries, are ignored in the tool path replay. | |||
You can use Offset Groups and Features when defining geometry. |

![]() |
In R13, the behavior of offset group has changed and is now similar to that of 3 Axis Surface Machining. | |||
![]() Collision Checking is also available. |

Multi-Axis Sweeping: ToolsRecommended tools for Multi-Axis Sweeping are End Mills, Face Mills, Conical Mills, T-Slotters and barrel tools. In general, you should choose:

Multi-Axis Sweeping: Feeds and SpeedsIn the Feeds and Speeds tab page, feedrates for approach, retract and
machining as well as a machining spindle speed. A Spindle output checkbox is available for managing output of the SPINDL
instruction in the generated NC data file. Feeds and speeds of the operation can be updated automatically according
to tooling data and Multi-Axis Sweeping: MacrosGeneral information about macros can be found in
NC Macros. |
