Tilted with the Angle

Introduction

When using Tilted with the Angle, the tool axis is tilted from the surface normal direction towards the Tilt Axis. The Tilt Axis can be the X-, Y-, Z-axis, or any user defined line. Imagine that the tilt axis and surface normal span a plane, the tool tilts on this imaginary plane.

Pole Limit Example

In this example the slot mill is supposed to be tilted 45 degrees towards the Z-axis. The drive face is a half sphere, the toolpath is a spiral. If the Pole Limit check box is selected then the tool never tilts beyond the selected tilt axis. In the image, you can see that the tool is tilted only until the point when the tool axis is parallel to the Z-axis.

 

 

 

This is the same toolpath with Pole limit turned off. The tool now over-tilts the tilt axis.

When the surface normal is parallel to the selected tilt axis, no plane can be spanned. The result is that the tool axis won't be tilted although you have set a tilt angle.

Example

In the example the tool axis (2) is tilted 45 degrees (3) towards the defined tilt axis (1) from the surface normal direction (4). You can see how the surface normal (4) and the tilt axis (1) span a plane in which the tool tilts.
