Thread Feature Parameters

Introduction

This topic explains the Feature page of the Lathe Wizard for a Thread feature. This topic will explain the options, provide images, and provide a link to the next topic.

The Feature page

The purpose of Threading is to create a helical gouge, whose pitch and attributes are well defined and consistent, in the part, in order to join another part with corresponding threading. The Threading feature offers one operation, the Lathe Thread, and the Feature page will allow you to set Rapid values, set the Feature Type and Region and add extensions to the existing geometry if necessary.  

 

Material Approach

Rapid Plane - is the height at which the tool can rapid safely within a single operation.

 

Default Rapid

Higher Rapid Value

 

Feature Parameters

Feature Type

  • OD - Sets the feature to the outer diameter of the part.

  • ID - Sets the feature to the inner diameter of the part.

  • Face - Sets the feature to faces normal to Z+.

  • Back Face - Sets the feature to faces normal to Z-.

 

 

 

Region - Sets the features default settings for the type of toolpath being used. This will set the default rapids, entry and exits as well as default tool selection and direction of cut.

 

  • 1 - See examples.

  • 2 - See examples.

Note: Region selections are not only for particular sections of the part. Even though, for a given situation, a particular region choice will set the feature up to be better suited for the task, the user may adjust the remaining parameters to match their particular needs.

 

 

 

Extension

Extensions allow you to extend the feature geometry without the need to create additional CAD geometry. The extension will be added or subtracted along the chain of entities.

 

- No extension will be added to the feature geometry.

- Will allow you to define an extension to the feature geometry.

Start and End Extensions

Start Extensions

 

Start - is the first of the selected chain of entities.

 

  • Distance- sets the amount of extension added to the tangent direction of the chain.

 

End - is the last of the selected chain of entities.

 

  • Distance - sets the amount of extension added to the tangent direction of the chain.
