|The information in this section will help you create and edit Multi-Axis
Sweeping operations in your Machining program.
Click , then select the geometry to be machined .
More information can be found in Selecting Geometry.
A number of strategy parameters are available for defining:
The Stepover tab has been renamed into Radial tab.

(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 tool axis definition depends on the Tool axis mode. The tool axis
arrow turns white when its definition box is not available
A click 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.
Lead and Tilt
In this mode the tool axis is normal to the part surface with respect to
a given lead angle (alpha) in the forward tool motion and
There are several guidance modes as follows:
Fixed lead and tilt:
Variable lead and fixed tilt:
Fixed lead and variable tilt:
|The purpose of the variable modes is to avoid collisions between the part to machine and the tool.|
Thru a Point
The tool axis passes through a specified point. The tool axis can be oriented To the point or From the point.
Normal to Line
The tool axis passes through a specified curve, and is normal to this
curve at all points.
Click the point in the sensitive icon and select a line in the graphic
Then decide whether the tool axis is defined from that line
The tool axis is allowed to vary from the specified lead angle within an
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
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.
(Double-click the part operation and push the Machine icon to open the
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:
The tool contact point will be visualized during tool path replay.
Cutter compensation instructions are not automatically generated in the
NC data output.
You can specify the following Geometry:
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.
Recommended tools for Multi-Axis Sweeping are End Mills, Face Mills, Conical Mills, T-Slotters and
In general, you should choose:
In 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
You can define transition paths in your machining operations by means of
