Machining
Parameter Description
Tool Path Style

Specifies tool path style.

Zig-zag The tool path alternates directions during successive passes.
One-way The same machining direction is used from one path to the next.
Helix The tool moves in successive concentric passes from the boundary of the area to machine toward the interior. The tool moves from one pass to the next by stepping over.
Concentric The tool follows successive arc motions.

Direction of Cut

Specifies how machining is to be done:

  • Climb milling: The front of the advancing tool (in the machining direction) cuts into the material first.
  • Conventional milling: The rear of the advancing tool (in the machining direction) cuts into the material first.

Machining Tolerance Specifies the maximum allowed distance between the theoretical and computed tool path.
Fixture Accuracy Specifies a tolerance applied to the fixture thickness. If the distance between the tool and fixture is less than fixture thickness minus fixture accuracy, the position is eliminated from the trajectory.
Type of Contouring Specifies the type of contour.

Circular The tool pivots around the corner point, following a contour whose radius is equal to the tool radius
Angular The tool does not remain in contact with the corner point, following a contour composed of two line segments
Optimized The tool follows a contour derived from the corner that is continuous in tangent
Forced Circular Creates tool paths comprising of portions of circular arcs (for example, when grooves are present along the trajectory and the tool is too big to penetrate).

Close Tool Path Specifies whether or not the program must close the tool path.
Tool Position ON Guide Specifies the position of the tool tip on the guiding elements. The system already accounts for Offset on contour and driving mode.
Percetage Overlap Specifies the amount that the tool must go beyond the end point of a closed tool path according to a percentage of the tool diameter.
Compensation Output Manages the generation of cutter compensation (CUTCOM) instructions for the pocketing operation side finish pass.

None Both the tool and cutter profile are visualized during tool path replay. Cutter compensation instructions are automatically generated in the NC data output.
Note: An approach macro must be defined to allow the compensation to be applied.
2D Radial Profile The tool is visualized during tooltip path replay. Cutter compensation instructions are automatically generated in the NC data output.
Note: An approach macro must be defined to allow the compensation to be applied.
2D Radial Tip Cutter compensation instructions are not automatically generated in the NC data output. However, CUTCOM instructions can be inserted manually. For more information, see Procedures for Generating CUTCOM Syntaxes
Extended Radial Profile Generates Angular contours in sharp corners of a part.

Compensation Specifies the tool corrector identifier to be used in the operation. The corrector type, corrector identifier, and corrector number are defined on the tool. When the NC data source is generated, the corrector number is generated using specific parameters.

  • Output point
  • Guiding point
Roughing Removes material before the bottom finishing paths.

  • Only cylindrical or conical bottoms are accepted.
  • If selected:
    • The Air Cut Optimization parameter is available. See
    • The Offset on Island Contours is available. See

Finishing See Strategy Parameters > Prismatic Finishing Strategy Parameters
Concentric Tool Path Style Parameters
The trajectory created by the Concentric strategy adapts itself dynamically to ensure a safe cutting at nominal speed. The engagement of the tool is controlled to never exceed a maximum value, even in corner areas.
This style is most suitable for hard-material milling, such as milling titanium, stainless steel, and ceramic materials where the tool needs to be protected. Other tool path styles, which are based on a constant distance between passes, are not appropriate because the tool load increases significantly when milling the inside of a radius.
The Concentric style controls the tool load by modifying, for each motion, the distance between passes. As a result, the tool lifetime is increased and the machining time is optimized.
Radial Strategy Parameters
Parameter Description
Sequencing Specifies the order in which machining is done.

Radial first Radial machining occurs first, then axial.
Axial First Axial machining occurs first, then radial.

Side Step First Handles each disconnected guide for all the passes (radial, axial, and finishing). Then the tool moves to the next guide and finishes all the passes for that guide.
Mode

Specifies how the distance between two consecutive paths is computed:

  • Maximum distance between paths
  • Step over ratio

  • Tool diameter ratio
  • Step over ratio
Distance Between Paths Defines the maximum distance between two consecutive tool paths in a radial strategy.
Number of Paths Specifies the number of tool paths in a radial strategy.
Overhang for Rework Areas Allows a shift in the tool position with respect to the soft boundary of the rework area.

Automatic Draft Angle Specifies the draft angle to be applied on the sides of the pocket.
Breakthrough Specifies the distance in the tool axis direction that the tool must go completely through the part. Breakthrough is applied on the bottom element, which must be specified as soft.

Side Thickness on Bottom Specifies the thickness of material left on the side by the bottom finish pass.
Bottom Finish Thickness Specifies the thickness of material that is machined by the bottom finish pass.

  • If the point is out of limits in the A, B, or C-axis, the tool axis is corrected and locked in the position limit.
  • If the point with the corrected axis is in collision, the point is removed.

When you select several check boxes, the most appropriate one is applied to any given point.

  • Tool pass: When the tool is in contact with the part, you can define a Fanning Distance.
    Note: Entering 0mm deactivates the Fanning Distance.
  • Retract macro: A retract pass is added to reconfigure the machine.
Notes:
  • If problems subsist after computing the tool path with those options, a message is displayed.
  • These corrections apply to the tool path of the current machining operation.
  • The machine configuration on the first point of the current machining operation is seen as the result of a motion from the Home position to this first point. Thus, it may differ from the actual one, resulting from previous machining operation and machine instructions.
  • Angular variations between two points cannot be detected on the first point of the tool path, because the position of the machine before this point is unknown.
