Updated Stock model
SolidCAM calculates the Updated Stock model (USM) according to the SolidVerify Accuracy Settings.
Two modes are available for the USM calculation: Automatic and Manual. The mode can be specified for the CAM-Part in the SolidVerify tab of the Updated Stock calculation page in the Part Settings dialog box.
Automatic mode
In the Automatic mode, SolidCAM automatically calculates the Updated Stock model for the operations chosen for simulation.
To generate the USM for the chosen operation, SolidCAM runs the SolidVerify simulation of all the previous operations in an invisible mode. The resulting Updated Stock model is saved in a *.stf file in the CAM-Part folder.
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 calculation settings. Saved USM files can be used in further SolidVerify simulations.
If the USM file for some operation already exists, SolidCAM checks the compliance between the accuracy settings of the USM and the SolidVerify 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-Part settings.
The Delete Updated Stock files command in the Settings menu of the SolidVerify simulation enables you to erase all the USM files of the current CAM-Part. This command is unavailable in the Manual mode.
Manual mode
In the Manual mode, SolidCAM enables you to manually save the USM after the SolidVerify simulation and use it for additional simulations.
When the Manual mode is chosen, the Save Machined stock to file and Load Machined stock from file buttons are available in the SolidVerify simulation toolbar.
When the simulation for a separate operation or for a number of operations is performed, 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.
SolidCAM enables you to load the USM of previous operation (if it was saved) using the Load Machined stock from file button and perform the simulation on it.
SolidCAM automatically deletes USM files for the specific operation when:
the operation was deleted;
the operation was changed and caused deletion of the operation PCode;
the operation sequence was changed;
the accuracy parameters were changed;
the working mode was changed 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 USM files generated for the SolidVerify simulation instead of Updated Stock model files for 3D Milling and vice versa.
If the USM file for 3D Milling is already generated for some operation it can be used also for SolidVerify simulation if the accuracy settings of the USM match the SolidVerify Accuracy Settings of the CAM-Part.
