Multi-Spindle Machining¶

Geometry or Cost Engine Changes that Could Impact Configured Digital Factories¶

The following changes might impact costing, even for Digital Factories that use earlier cost model versions.

Chains of Adjacent Surfaces (impacts operation assignment, tool selection, and cycle time): this release provides enhanced geometry recognition to identify chains of adjacent surfaces that are likely to be finished with the same side milling tool.

Additionally, this release improves recognition of fillet surfaces that can be machined indirectly by the radius of a bull nose end mill. Now such fillet surfaces are more likely to be assigned Indirect Filleting operations instead of a less-realistic finish machining operation.

As a result of this change, cycle times may change slightly, compared to the previous release.

Note:

To access this improved functionality you must use the latest cost model version for the Machining process group (CMV 300). In addition, you must use the latest cost model version for Multi-Spindle Machining (CMV 40).

Set the site variable parallelSurfaceChainAlgorithm as follows, depending on your cost model version:
- Open Chain (default), if you are using the latest cost model version
- Closed Loop, if you are using a prior cost model version
Important:

By default, the site variable parallelSurfaceChainAlgorithm is set to Open Chain, so you must change the value to Closed Loop if you do not upgrade your Multi-Spindle Machining and Machining cost model versions.

Bug Fixes or Small Improvements to Prior Cost Model Versions¶

The following changes might impact costing for Digital Factories that use earlier cost model versions.

Cost Model Changes that don't Affect Configured Digital Factories¶

The following changes do not affect costings with Digital Factories that use earlier cost model versions. The changes are available only in the latest cost model version.
