Stock Definition
This page enables you to define the settings for the 3D Box and Cylinder modes of Stock model definition.
3D Box Stock Definition
This section enables you to specify the defaults for 3D Box Stock model offsets and the method of their definition.
When the SolidCAM Settings values option is chosen, the default offsets can be specified in the Box Offsets section.
When the Previous CAM-Part values option is chosen, the default offsets defined in the last CAM-Part that was open in SolidCAM will be used.
Mode
When the Relative to model option is chosen, the box is defined by offsets from the solid model faces.
When the Absolute coordinates option is chosen, the box is defined by specifying coordinates relative to the CAM-Part Coordinate System.
Take model dimensions
With this option, for each new Stock created in this mode, the absolute coordinates are taken automatically from the model. The same result can be achieved if you click the Take model dimensions button in the Model dialog box.
Cylinder Stock Definition
This section enables you to specify the defaults for Cylinder Stock model offsets and the method of their definition.
When the SolidCAM Settings values option is chosen, the default offsets can be specified in the Cylinder Offsets section.
When the Previous CAM-Part values option is chosen, the default offsets defined in the last CAM-Part that was open in SolidCAM will be used.
Mode
When the Relative to model option is chosen, the box is defined by offsets from the solid model faces.
When the Absolute coordinates option is chosen, the box is defined by specifying coordinates relative to the CAM-Part Coordinate System.
Take mode dimensions
With this option, for each new Stock created in this mode, the absolute coordinates are taken automatically from the model. The same result can be achieved if you click the Take model dimensions button in the Model dialog box. You can choose either the Internal Diameter Offset or Internal Diameter.
3D model Offset definition
3D Model Offset parameters can be set with default values in this section.
Tolerance
By default, the Tolerance value is set at 0.2. Tolerance is the value you aim to attain in the end for the mesh. The Tolerance is used to decimate the geometry after any offset.
Offset
By default, the Offset value is set at 0. This option offsets the facet model by the value set in this field. The value entered in this field must be positive or equal to zero.
Precision
By default, the Precision value is set at 1. Precision is defined as the grid-distance between the surface intersection rays. The resulting accuracy is defined as the distance between the simulated surface and the theoretically "perfect" surface, as defined by the initial stock, tools and tool path.

1. The chosen Precision does not correspond directly to the calculation accuracy of the simulation. While the grid distance is given by the chosen precision value, the positional accuracy along the ray is far higher (limited by calculation accuracy). The resulting deviation between the model surface and the perfect surface depends on the geometry. 2. Precision will influence the calculation time and if you set a large value, SolidCAM might miss the geometric features completely as the Tolerance is used for decimation later. Precision will be the main parameter influencing the number of triangles generated. |
