Stock Setup tab – Mill/Router Mastercam

• Selecting the type of stock model

There are several ways to create stock models depending on your needs.

• Choose Rectangular or Cylindrical to create simple stock models that are not defined by any actual geometry. All the dimensions are entered in this dialog box and no geometry is added to your part file. You can choose whether or not to Display the stock on the screen.
• Choose Solid to use a solid model inside your current part file as the stock.
• Choose File to use a solid model from an STL file as the stock model.
• Setting the stock dimensions

Mastercam gives you several techniques for setting the stock dimensions. You can type the dimensions directly into the X, Y, and Z fields, or use the following methods when you don’t know the exact dimensions:

• Choose Select corners to return to the graphic window and select the two opposing corners of a 3D rectangle.
• Choose Bounding box to have Mastercam calculate the furthest points in your part geometry.
• Choose NCI extents to have Mastercam calculate the furthest points in your toolpaths, based on just the feedrate moves.

Mastercam will automatically enter the stock dimensions in the fields. You can then edit them as needed.

• Setting the stock view

Select a stock view to properly orient the stock model with respect to your part. You can align the stock model to any named view saved in your part file. When you choose a stock view, the edges of the stock model will be parallel with the axes of the selected view.

Select a stock view when you will be creating toolpaths in a work coordinate system (WCS) other than Top and want to align the stock model to your part. If you have several toolpaths in the machine group that use more than one WCS, Mastercam will use the stock view to keep the stock model constant when the WCS for each operation changes. Mastercam stores the stock view with the stock definition, independent of the WCS.

To select a stock view, click the Stock View button and select the view from the View Selection dialog box.

Note: If you change the stock view, you might need to reset the stock origin.

• Setting the stock origin

Use the stock origin to locate the stock relative to your part. First, you need to choose a point on the stock to use for the stock origin. In the dialog box, the cross shows you where the stock origin is:

The default position is the middle of the stock. Click on a corner of the part to set it as the stock origin. For example, router users often want the stock origin on the bottom of the part.

Then, enter the coordinates of this point in the Stock origin fields, or click on the Select button to choose the point from the graphics window.

Note: Use the Verify function to perform gouge checking.
