Creating a Workpiece Automatically

The workpiece is a model that represents the full volume of all the mold components that are needed to create the final mold model.
• The workpiece displays transparent green in the graphics window.
• The automatic workpiece accuracy is automatically matched to the reference model.
• The workpiece creates multiple shapes:
– Standard Rectangular
– Standard Round
– Custom

Once you assemble the reference model into the mold model, you typically create and assemble the workpiece next. The workpiece is a model that represents the full volume of all the mold components (cavity, core, and inserts) that are needed to create the final mold model. The workpiece icon that displays in the model tree is different than that of a conventional part model and the reference model, which is shown in Figure 1. The workpiece displays transparent green in the graphics window.

To automatically create a workpiece, select Automatic Workpiece the Workpiece types drop-down menu. The workpiece is automatically
assembled to the Mold Origin coordinate system using the Coord Sys assembly constraint, and the accuracy is automatically set to match that of the reference model.
To create an automatic workpiece, you must specify the following items:
• Mold Origin – The Mold Origin is a mold model coordinate system from which directions are determined for workpiece creation.
• Shape – The shape determines the shape of the workpiece. The system creates a workpiece with the minimum dimensions that the reference model fits in, within the specified shape. The following options are available:
– Standard Rectangular – This creates a rectangular workpiece using Create Rectangular Workpiece , which is shown in Figure 2.

– Standard Round – This creates a round-shaped workpiece using Create Round Workpiece , which is shown in Figure 3.
– Custom – Custom creates a custom-shaped workpiece using Create Custom Workpiece
.
• Units – This specifies the system of units for the workpiece. You can select inches or millimeters.
• Offsets – This enables you to specify the offset values to add to the dimensions of the workpiece, based on the mold origin. The offsets depend on the shape of the workpiece that you have selected. You can specify each offset individually, or specify all offsets uniformly. The following offset options are available:
– X-direction – This adds material in the positive or negative X-direction.
This offset is available for only the Standard Rectangular shape and some custom shapes.
– Y-direction – This adds material in the positive or negative Y-direction.
This offset is available for only the Standard Rectangular shape and some custom shapes.
– Z-direction – This adds material in the positive or negative Z-direction.
– Radial – Radial adds material in the positive radial direction.
– Uniform Offsets – This adds material in the positive and negative X-, Y-, and Z-directions, and Radial, where applicable.
• Overall Dimensions – The overall dimensions get updated when you specify offset values. However, you can also specify the overall dimensions, and the offset values get updated automatically. You can manually specify the X and Y dimensions for rectangular and custom workpieces, and the Diameter for rounded workpieces, to customize the workpiece size. You can manually specify the Z Cavity and Z Core dimensions for all workpieces to customize the size.
• Translate Workpiece – This enables you to specify the translation values for the X- and Y-directions to position the workpiece around the reference model.
You can modify the default Workpiece Name. The Workpiece Name is the name of the workpiece component as it displays in the model tree. By default, its name is of the format MOLD-MODEL-NAME_WRK, which is shown in Figure 1.
