Patterns

Method

 

  • 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.

 

 

Thread Type

 

  • Inside - the  toolpath creates an internal thread.

  • Outside - the toolpath creates an external thread.

 

 

Side Roughing

 

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.

 

 

 

Compensation


System Compensation

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

 

  • On - the toolpath is calculated based on the radius of the tool.

  • Off - the toolpath is calculated from the center line.

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.

 

Parameters

Thread Parameters

 

  • Thread Library

    Select this check box to select a thread as defined in the Thread Library.

    Clear the check box to enter threading parameters manually.

  • Thread Diameter - is the major diameter of the thread for internal or external threads.

  • Thread Height - sets the distance from the minor diameter to the major diameter of the thread.

  • Thread Pitch - sets the distance between the top of each thread.

  • Threads Per Revolution - sets the number of threads generated per revolution. The system automatically calculates the number of revolutions required based on the Thread Height and Thread Pitch values.

  • Taper Angle - allows you to set the angle for a tapered thread.

 

Taper From

 

  • Top - sets the origin of the taper from the top of the hole.

  • Bottom - sets the taper from the bottom of the hole.



 

Other

Direction

 

  • Right Hand - the thread is clockwise.

  • Left Hand - the thread is counter-clockwise.

 

 

  • Thread Start Angle - defines the angle from the X-axis at which the thread milling starts. This is always applied at the top of the feature regardless of using Top Down or Bottom Up.
