Info

Before you begin Make sure your unit of measure is set to Inch before you begin this project. To set the system unit to Inch: 1. On the Tools menu, click Units. 2. Select Inch. Units menu Open the project file 1. On the Main toolbar, click Open. 2. Open the file GetStarted 2D Milling-1.SCPRT For this project you will learn how to use the following 2 Axis commands: • Face Mill • Pocket • Drill • Chamfer Mill For details about other commands on the NC > 2 Axis menu, please refer to SURFCAM Help. 64 | Get Started with SURFCAM
Step 1: Face the material Face milling typically uses face mills, shell mills, and fly-cutters to clear a relatively thin layer of material over the top of a part. This provides a uniformly flat starting surface for subsequent milling operations. SURFCAM designed its Face Mill operation to be as simple as possible, without losing any needed functionality. SURFCAM’s Face Mill operation provides optimal performance as follows: • Stepovers are adjusted to the part width to insure a constant width for all material cuts. A constant width of cut decreases the wear on the tool and machine. • You can elect to reduce burrs with a climb cut along the part edge on the final cut (available only for the Zig and Zig Zag face methods). • You can make use of the large side step (at shallow depths) capability of face mills, shell mills and fly-cutters. Side steps can be set to up to 90% of the tool diameter. • The tool is never allowed to plunge into the material. Every face mill toolpath begins at the cut depth at a user-defined distance outside the selected geometry. Facing Methods • Zig: The tool is repositioned after each pass so that all cuts are created in the same direction. • Zig Zag: The tool moves in a back-and-forth pattern. • Spiral: The tool starts at the outside and moves inward, maintaining the cutting method (climb or conventional). For this project, you will face the stock with a 3-inch face mill to remove 0.010 of material from the top of the part. You will use a Spiral facing method. The rapid plane is located 1 inch above the part. 1 On the NC menu, click 2 Axis and then click Face Mill Project 2 • Mill a Production Part | 65
