Basic 3-Axis Trajectory Milling

In 3-axis trajectory milling, you specify the tool trajectory by creating cut motions using the customize functionality.

• To configure the toolpath, you must specify the trajectory of the control point of the tool by creating cut motions using the customize functionality.
• You can specify the trajectory type using the following options.
– Sketch – Sketch a trajectory.
– Edge – Use model edges.
– Curve – Use datum curves.
– Surface – Use surfaces (at a specified height).
• After you specify the trajectory type, you then need to configure the cut motion options from the following list. Note, you can configure some or all of these options depending on the selected trajectory type.
– Configure Trajectory
♦ You can configure a sketch, edge, curve, or surface.
– Direction – You can specify the direction of trajectory.
– Offset – Specify the direction in which the cut motion is offset (none, left, or right). The offset distance is half of the cutter diameter.
♦ The direction of the offset corresponds with the direction of trajectory.
When you select an offset option, the arrow shows the offset direction.
– Start Height – Select the height from which you want the tool tip to start.
– Height – Adjust the depth of the final pass of the tool by selecting a plane. By default, Creo Parametric uses the height of the configured
trajectory reference.
– Material Side – If the offset direction is none, then you can specify the material side to be left or right.
• Within the Customize dialog box, there are many options to provide more low-level control over the toolpath. For example:
– You can add or remove cut motions.
– You can modify feed rates.
– You can add user-defined approach and exit motions.
