Patterns

Introduction

This topic explains the Patterns page of the Mill Thread operation parameters found in the Mill Thread Wizard.

Top Down - the tool starts the cut at the top of the thread and departs from the cut at the bottom of the thread.
Bottom Up - the tool starts the cut at the bottom of the thread and departs from the cut at the top of the thread.

Select this check box to create a side roughing pattern that will create the thread in multiple steps.

Clear the check box to create the thread in a single pass.

Additional Passes - adds passes to the single pass thread creation.
Pass Amount - sets the spacing of the additional passes from the final thread creation pass.

System Compensation

With this option On, the system offsets the geometry by the tool radius. With this option Off, you should use Machine Compensation.

- Off- the toolpath is calculated from the center line.
- On- the toolpath is calculated based on the radius of the tool.

Machine Compensation

These options only effect the output in the posted code.

Off - no cutter compensation codes are output in the posted program.
Left (G41) - the toolpath of the operation represents the center of the cutter. The post processed code includes the command for cutter compensation to the left of the contour.
Right (G42) - the toolpath of the operation represents the center of the cutter. The post processed code includes the command for cutter compensation to the right of the contour.
