Creating Rectangular Stock with 2D Geometry

Introduction

In this example you learn how to create rectangular stock using sketch entities. This example will also provide links to related topics.

Creating the Stock

You select the stock type, size, and add offsets to the stock as needed. The sketch used for this example is shown first.

 

Part 1) Select the Stock Type

1. When the Stock Wizard is entered for the first time, Rectangular will be highlighted for the Stock Type by default, and stock will automatically be calculated from the geometry found in the graphics area.

 

This is because the Auto from workspaceoption is selected by default.

 

 

Notice also that the stock coordinate system is placed at the top and center of the stock. This can be adjusted In the Stock Orientation group, and is only a coordinate system used in setting the stock origin and orientation, and it is not related to the machining origin.

Part 2) Pick Geometry

Because you are only creating stock for the part and not the entire print, you must manually select the desired geometry.

 

1. In the Size group, under Geometry Options, select Pick from the drop down.
   

 

2. Select the profile to create the bounding stock as shown next.

 

The geometry is added to the list.

3. To create stock based on the selection, click Calculate Stock.
   
   The result is shown next.

 

Part 3) Set the Stock Size

Now that the stock shape is defined, and because you are using 2D geometry, you need to change the default stock height.

 

Note: The stock uses a default one inch height when there is no difference between the extents of the geometry in the Z-axis (when using sketch geometry). Otherwise, the stock height is set from the difference in the geometry extents.

 

1. In the Size group, select Enter.Click in the (Height Z) box, type 2.000, and press Tab .
   
   The height of the Stock is creased.

 

Part 4) Add an Offset to the Stock

Because the part is being cut from stock that is larger than the bounding stock, an offset is added to increase the size. A diagram of the Offset directions follows.

 

Offset Diagram
-X - the negative X-axis direction. +X - the positive X-axis direction. -Y - the negative Y-axis direction. +Y - the positive Y-axis direction. -Z - the negative Z-axis direction. +Z - the positive Z-axis direction.

 

1. In the Offset group, enter the values as follows.
   
   

	X	Y	Z
Offset +			0.0000
Offset -			0.0000

 

The stock is now 0.2500 larger on all four sides.

 

2. To finish the Stock Specification, click Next to go to the Machine Setup dialog.
