Using Workpiece Models

It is important to understand how workpiece models are used in manufacturing assemblies.
Workpieces represent unmachined stock material, for example:
• Stock Billets
• Castings
Workpiece Features:
• Enable machining simulation of workpiece.
• As-machined versions.
• No machining outside workpiece boundaries.
• Workpiece display.
Workpiece Options:
• Create an automatic workpiece.
• Assemble using Same Model option.
• Assemble with inherited features .
• Assemble with merged features.
• Create a manual workpiece.

Workpieces represent the unmachined stock material. They are optional components within a manufacturing model; however, if they are used, then you can simulate the machining of workpieces when creating NC sequences.

Workpieces can be standard stock billets or they can represent castings.
Using workpieces provides you with a number of capabilities:
• You can simulate the cutting tool machining the workpiece.
• After creating each toolpath, you can update the workpiece to display an as-machined version of the workpiece.
• Unless you specify otherwise, there is no machining outside the workpiece boundaries.
• The workpiece is displayed in green to help you visually distinguish between the workpiece and the reference model geometry. In addition,
when the display style is set to shaded, the workpiece is displayed as semi-transparent. This enables you to view the reference model geometry
which would normally be obscured by the workpiece.

Workpiece Options
You can assemble or create a workpiece in a manufacturing model. A number of options are available:
• Create an automatic workpiece – This enables you to create a rectangular or round workpiece depending on your requirements. A dashboard
interface enables you to easily control the size and position of the workpiece relative to the reference model.
• Assemble a workpiece using the Same Model option – This enables you to assemble an existing part into the manufacturing model as the workpiece.
• Assemble a workpiece with features inherited from a selected part. The new workpiece inherits geometry and feature information from the selected part. At any time, you can specify the geometry and the feature data that you want to modify on the workpiece without changing the original part.

Inheritance provides greater freedom to modify the workpiece without changing the original part.
• Assemble a workpiece with features merged from a selected part. In this case, a new workpiece part is created. The new workpiece contains an external merge feature, and this feature contains all geometry and datum features which have been copied from the originally selected part. All layer information is also copied into the new workpiece.
• Create a manual workpiece – This enables you to create a new workpiece in the manufacturing model by manually creating features and geometry as required.
