Updated Stock model calculation

SolidCAM offers two modes of Updated Stock model calculation: Automatic and Manual. The mode can be specified for the CAM-Part with the Updated Stock calculation page in the Part Settings dialog box. The same modes are used for the SolidVerify Updated Stock model calculation.

Automatic mode

During the operation calculation process, SolidCAM runs the SolidVerify simulation of all the previous operations in the invisible mode. The resulting USM is saved in *.STFrm file in the CAM-Part folder. SolidCAM calculates the USM according to the Updated Stock Accuracy Settings.

During the USM calculation process for the current operation, SolidCAM generates intermediate USM files for the previous operations and saves them according to the Updated Stock model method. The saved USM files can be used for the Rest material calculation of additional operations. These intermediate Updated Stock model files are removed when the CAM-Part is closed.

If the USM file for some operation already exists, SolidCAM checks the compliance between accuracy settings of the USM and Updated Stock Accuracy Settings of the CAM-Part. If these settings concur, SolidCAM uses the existing USM, otherwise the USM is recalculated in accordance with the CAM-Parts Settings.

Manual mode

In the Manual mode, SolidCAM enables you to save the USM manually after the SolidVerify simulation and use it for the Working area definition with the Cut only the Rest material option.

When the simulation of a separate operation or a number of operations is performed in the SolidVerify mode, the Save Machined stock to file button enables you to save the USM in the *.STF file. The name of the file is the same as the name of the last simulated operation.

In the Machined Stock name box, you can choose any previously saved USM.

SolidCAM automatically deletes Updated Stock model files for a specific operation when:

  • the operation was deleted;

  • the operation was changed and it caused the deletion of the operation PCode;

  • the operation sequence was changed;

  • the accuracy parameters were changed;

  • the working mode was switched from Manual to Automatic.the working mode was switched from Manual to Automatic.

Updated Stock Model interchangeability

Updated Stock models generated for the SolidVerify simulation and for 3D Milling of Rest material areas are interchangeable. This means that SolidCAM can use Updated Stock model files generated for the SolidVerify simulation instead of Updated Stock model files for 3D Milling and vice versa.

If the USM file for SolidVerify simulation is already generated for some operation, it can be used also for Rest material if the Accuracy settings of the USM match the Updated Stock Accuracy settings of the CAM-Part.
