The Stock dialog box provides you with a place to change all of the settings used for the current part stock. To display the dialog box, right-click Milling Stock and click Edit.
BobCAM supports two different types of stock for milling, rectangular and cylindrical. If the Stock Geometry has been set for this stock, many of the following parameters are unavailable because the selected geometry dictates the shape of the stock. Both stock shapes use different parameters and are detailed separately next.
Rectangular Stock
The Rectangular Stock shape is the standard cube of stock most often used in two and three axis milling.
Stock Definition
Material - The type of material comprising the stock.
Type - Select rectangular or cylindrical stock type.
Name - Displays the name of the stock. Currently only one stock is supported at a time so the name cannot be edited.
Z Top Of Stock - Sets the Z-axis of the top surface of the material.
Stock Length (X) - This sets the size of the stock rectangle in the X-axis.
Stock Width (Y) - This sets the size of the stock rectangle in the Y-axis.
Stock Thickness - Set the thickness of the stock. This is always a positive value and extends downward from the Z Top Of Stock setting.
Rotary Axis - Select the X-axis or Y-axis as the stock rotation axis.
Clearance
Clearance Plane - This value sets the global retract plane for the entire stock. It is taken into account in every feature under this stock in the tree.
Work Coordinate Offset
Work Offset # - If the stock is set up to use a specific work offset on the machine, select the proper offset here.
Cylindrical Stock
Cylindrical Stock is used in 4 axis parts where the Y-axis length of the toolpath is converted into the A rotary axis. It is also used for 4th axis indexed parts that change rotations only once at the beginning of a feature. The post processor must be configured to use a rotary axis and cylindrically-shaped stock in order for this stock type to be valid.
