Understanding Trajectory Milling

Trajectory milling enables you to sweep a tool along any user-defined trajectory. You can use it for milling slots or chamfers.
Trajectory Milling
• Two Types
– 2-Axis Trajectory Milling
♦ Select or sketch a curve.
♦ Curve must be planar.
♦ Simple to use.
♦ Automatic material removal.
– 3- to 5-Axis Trajectory Milling
♦ Interactively configure trajectory.
♦ Create cut motions.
♦ More advanced options.
Sketched or Edited Tools
• Edited Tools
• Sketched Tools – User-defined tool control point.

There are two types of trajectory milling sequences:
• 2-Axis Trajectory Milling

Figure 3 – Sketched Tool
– To configure the toolpath for 2-axis trajectory milling, you sketch or select a curve that represents the final trajectory of the control point
of the tool.
– The curve must lie in the plane normal to the Z-axis of the NC sequence coordinate system.
– In the simplest case, the tool makes just the one cutting pass along this trajectory, with or without tool offset.
– This type of trajectory milling sequence also benefits from automatic material removal.
• 3- to 5-Axis Trajectory Milling
– To configure the toolpath for 3- to 5-axis trajectory milling, you must interactively specify the trajectory of the control point of the tool by
creating cut motions using the customize functionality.

Sketched or Edited Tools
• You can use either edited tools or sketch your own tool for the NC sequence.
• If you sketch a tool, you can create a user-defined control point for the tool
