LESSON 3
The Rest Roughing Toolpath
3
Before you apply the finishing toolpath, the part needs further roughing. The Rest Roughing toolpath is a good choice, because it removes only stock remaining from previous toolpaths rather than cutting the entire part. Here, you program the Rest Roughing toolpath that will smooth out the surface of the main phone cradle. The following picture shows the toolpath being cut on a Makino vertical machining center.
Lesson Goals Create a containment boundary from construction geometry. Set the toolpath parameters. Generate the Rest Roughing toolpath. Backplot and Verify the toolpaths.
Exercise 1: Creating the Toolpath CAUTION: The steps in this exercise describe only the key settings required to create the Rest Roughing toolpath for the phone cradle part. Your toolpath settings might vary depending on your selected parameters, including machine definition, tooling, material, toolpath type, surface finish requirement, and cycle time requirement. For this reason, as you work through this exercise, review all settings in each dialog box to ensure that the settings are correct for your machine.

LESSON 4
The Scallop Toolpath
4
With the roughing complete, it’s time to apply a finishing toolpath to the phone cradle’s surface. The high speed Scallop toolpath uses a 3D stepover distance that is measured along the surface, instead of parallel to the tool plane. This ensures a consistent scallop height, regardless of the surface direction. In this lesson, you create a Scallop toolpath to finish the surface of the main phone cradle. The following picture shows the toolpath being cut on a Makino vertical machining center.

LESSON 1
FBM Mill
1
About the FBM Sample Part Lessons 1 and 2 of this section introduce the Feature Based Machining (FBM) functions in Mastercam for SolidWorks. The following picture shows the part file as it displays in SolidWorks.
The part files included for the FBM portion of the tutorial are:
FBMPart01.SLDPRT—The file for starting the FBM section of the tutorial FBMPart02.SLDPRT—The file after completing Lesson 1 FBMPartComplete.SLDPRT—The FBM tutorial file after completing Lessons 1 and 2 FBM Mill is a powerful feature-based machining (FBM) strategy that analyzes a solid part, detects all machining features in a specified plane, and generates the 2D milling toolpaths needed to machine the detected features. In this lesson, you use FBM Mill to generate toolpaths for the part shown in the above picture. The goal is to generate toolpaths for the following operations:
Face the top surface Contour the part’s outside edges Cut the main pocket Cut the slots in the main pocket Cut the two large holes in the main pocket
74 • MASTERCAM FOR SOLIDWORKS TUTORIAL / FEATURE BASED MACHINING
Lesson Goals Set up a machine group. Define the part’s stock. Generate FBM Mill toolpaths. Modify FBM Mill parameters. Backplot and Verify the toolpaths.
Exercise 1: Setting Up 1 Load the part file FBMPart01.SLDPRT,
which was supplied with this tutorial. 2 So that you do not overwrite the original
during this tutorial, save the file as FBMPartTutorial.SLDPRT. 3 Optional: If you want to use a machine
definition other than the default: a From the Mastercam X5 menu, choose
Machine Selection, and then select your machine from the submenu. Mastercam for SolidWorks creates a machine group for the selected machine. b Click the Mastercam Toolpath
Manager tab to display the Toolpath Manager.
c Right-click Machine Group-1, and
select Groups, Delete from the pop-up menu. Mastercam for SolidWorks removes the old machine group, leaving only the one you created.
