Use Spindle Main Direction

Introduction

Use Spindle Main Direction uses the machine definition's main spindle direction as the reference for finding the side tilt direction. The side tilting always happens from the view defined by the spindle main direction vector. For example, if the spindle main direction vector is the Z-axis, and side tilting is 90 degrees from the surface normal, then the tool axis orientation is the surface normal rotated 90 degrees towards the spindle main direction. In practical terms, such a rotation can be handled by a machine tool without utilizing the C-axis.

You can add a lead angle and a side tilt angle and the tool will tilt from the surface normal to the direction of the main spindle axis. You can't use the side tilt definition andAllow Flipping Side Directiontogether. In this case Allow Flipping Side Directionis deactivated.

Example

• In this example the main direction is the Z-axis (1). With side tilt angle of 90 degrees the tool axis is oriented to this direction. In the following image (2) represents the tool axis and (3) represents the toolpath.
