Section 12D Toolpaths

L E S S O N 1

1General Setup - Mold CoreBefore generating toolpaths for a part, you must prepare Mastercam for SolidWorks and the part file. This preparation includes such tasks as selecting a machine definition and defining a tool plane. Failure to set up the part correctly will give unpredictable results. This lesson introduces the tutorial part files for Section 1, 2D Toolpaths and shows how to create a machine group.

Lesson Goals Explore the part files. Select a machine. Copy a toolpath.

About the Mold Core PartThe lessons in this section are based on the MoldCore.SLDPRT file, which is included with the tutorial. The following picture shows the part file as it displays in SolidWorks. This demo part contains nearly 20 operations, which demonstrate many of Mastercam for SolidWorkss 2D toolpaths.


This tutorial covers only two of the toolpaths: Facing and Area Mill.

Note: To fully machine the part requires more operations than are described in this book.

The part files included for this portion of the tutorial are:

2DToolpath01.SLDPRTThe tutorial file for starting Lesson 1 2DToolpath02.SLDPRTThe tutorial file for starting Lesson 3 2DToolpathComplete.SLDPRTThe tutorial file after completing Lesson 3 MoldCore.SLDPRTThe fully toolpathed part

Exercise 1: Selecting Your MachineToolpaths are contained in Machine groups. For this reason, your part file needs at least one machine group before you can toolpath the part. Mastercam for SolidWorks automatically creates a machine group for each machine you select from the Machine Selection menu item. To see how machine selection works, complete the following exercise.

1 Open the part file 2DToolpath01.SLDPRT, which was provided with this tutorial.

2 Save the part under the name 2DToolpath01Tutorial.SLDPRT.

Saving the part under a new name helps prevent your accidentally modifying the original file.

3 From the Mastercam X4 menu, choose Machine Selection, and then select your machine from the submenu.

Mastercam for SolidWorks creates a machine group for the selected machine.

Section 23D High Speed Toolpaths

L E S S O N 1

1General Setup - Phone CradleAs you learned in Section 1, before generating toolpaths for a part, you must prepare Mastercam for SolidWorks and the part file. Because the exercises in this lesson use a different part than the first three lessons, you need to set up the new part for your machine. As before, this preparation includes such tasks as selecting a machine definition and defining a tool plane. Failure to set up the part correctly will give unpredictable results. This lesson introduces the tutorial part files, as well as teaches you to set up the parts for toolpathing.

Lesson Goals Understand the part files. Select a machine. Create and set the tool plane. Define the stock.

About the Phone Cradle Sample PartLessons 1 through 3 of this section are based on the PhoneCradle.SLDPRT file, which is included with the tutorial. The following picture shows the part file as it displays in SolidWorks.


This tutorial covers only a subset of the toolpath types used to machine the part. These toolpath types are as follows:

Core Roughing Rest Roughing Scallop Waterline

Note: To fully machine the part (shown in the following picture) requires more operations than are described in this book.

The part files included for the phone cradle portion of the tutorial are:

PhoneCradle01.SLDPRTThe tutorial file for starting Lesson 1 PhoneCradle02.SLDPRTThe tutorial file after completing Lesson 1 PhoneCradle03.SLDPRTThe tutorial file after completing Lesson 2 PhoneCradle04.SLDPRTThe tutorial file after completing Lesson 3 PhoneCradle05.SLDPRTThe tutorial file after completing Lesson 4 PhoneCradleComplete.SLDPRTThe tutorial file after completing all lessons PhoneCradle.SLDPRTThe phone cradles full SolidWorks drawing, with no toolpaths

GENERAL SETUP - PHONE CRADLE 35

Exercise 1: Selecting Your MachineToolpaths are contained in machine groups. For this reason, your part file needs at least one machine group before you can add a toolpath to the part. Mastercam for SolidWorks automatically creates a machine group for each machine you select from the Machine Selection menu item. To see how machine selection works, complete the following exercise.

1 Open the part file PhoneCradle01.SLDPRT, which was provided with this tutorial.

2The Core Roughing ToolpathIn this lesson, you program the roughing toolpath that removes the majority of the material from the phone cradle. Because the feature to cut is a dome-shaped core, and because the tool can approach the feature from the outside, you will create an HST Core Roughing toolpath to rough out the part. The following picture shows the Core Roughing toolpath being cut on a Makino vertical machining center.

Lesson Goals Set a containment boundary. Set toolpath parameters. Generate the toolpath. Backplot and Verify the toolpath. Post the toolpath.

Exercise 1: Creating the Toolpath1 If necessary, load the file

PhoneCradleTutorial.SLDPRT that you saved at the end of the previous lesson.Alternatively, you can start this lesson with the file PhoneCradle02.SLDPRT.


CAUTION: The steps in this exercise describe only the key settings required to create the Core 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 situation.

L E S S O N 3

3The Rest Roughing ToolpathBefore 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.

4The Scallop ToolpathWith the roughing complete, its time to apply a finishing toolpath to the phone cradles 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 Goals Set Scallop toolpath parameters. Generate a Scallop toolpath. Backplot the toolpath. Verify the toolpath.


Exercise 1: Creating the Toolpath

CAUTION: The steps in this exercise describe only the key settings required to create the Scallop 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 situation.

Section 3FBM Toolpaths

L E S S O N 1

1FBM MillAbout the FBM Sample PartLessons 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.SLDPRTThe file for starting the FBM section of the tutorial FBMPart02.SLDPRTThe file after completing Lesson 1 FBMPartComplete.SLDPRTThe 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 following picture. The goal is to generate toolpaths for the following operations:

Facing the top surface Contouring the parts outside edges Cutting the main pocket Cutting the slots in the main pocket

Cutting the two large holes in the main pocket


Lesson Goals Set up a machine group. Define the parts stock. Generate FBM Mill toolpaths. Modify FBM Mill parameters. Backplot and Verify the toolpaths.

Exercise 1: Set Up1 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 X4 menu, choose Machine Selection, and then select your machine from the submenu.


b Click the Mastercam Toolpath Manager tab to display the Toolpath Manager.

FBM MILL 75

c Right-click Machine Group-1, and select Groups, Delete from the pop-up menu.


Exercise 2: Defining the StockFBM Mill requires that you set up stock for the part. The following exercise shows how to complete this task.

1 In the SolidWorks FeaturesManager, click the Mastercam Toolpath Manager tab.

The Toolpath Manager displays.

2 In your machine groups properties, select Stock setup. (If necessary, display Stock setup by clicking the + next to the Properties icon.)

Mastercam for SolidWorks analyzes the parts geometry and creates stock of the same size as the parts geometry.


4 Change the X, Y, and Z dimensions to 102, 152, and 27, respectively.

Now you have extra stock for a facing operation and to cut the outside contour.

5 Change the Z coordinate of the stock origin to 2.

This change takes all of the extra stock that is normal to the Z axis and places it above the parts front face, which is the tool plane.

6 Click OK.

The Stock Setup dialog box closes, and Mastercam for SolidWorks displays the stock as dashed red lines.

Exercise 3: Creating the Mill Toolpaths1 In the Mastercam X4 CommandManager,

click FBM Mill.

FBM Mill will now create rough and finish toolpaths for the outside edges of the part.

4 Deselect the Create as needed option.

Now FBM Mill can only use tools from the library selected in the Tool library box.

5 Click the Detect button.

FBM Mill analyzes the part to identify features to machine, and then displays the detected features in the Features page.

6 Click OK to generate toolpaths for the detected features.

The Enter new NC name dialog box displays.

7 Type a name for the NC file, and click OK.


FBM Mill generates all of the 2D operations needed to machine the detected features, as shown in the following picture.

Exercise 4: Customizing the ToolpathsNotice that FBM Mill identified the largest hole as a feature to cut, but missed the smaller, 20mm hole. In this exercise, you change the FBM Mill parameters to include the smaller hole.

1 In the Toolpath Manager, click the FBM Mill Parameters icon.

The FBM Toolpaths - Mill dialog box displays.

2 Select the Feature detection page.

FBM MILL 79

3 Change the Recognize holes greater than this diameter as features setting to 10.

The value of 10 ensures that FBM generates a toolpath for the 20mm hole that is located inside the pocket.


FBM Mill reanalyzes the part to identify features to machine and then displays the features in the Features page. Notice the new Zone 5 operation, which is the 20mm hole.

5 Click OK.

The dialog box closes, and Mastercam for SolidWorks marks the FBM Mill operation as dirty.

6 Click the Regenerate all dirty operations button.

FBM Mill regenerates the toolpaths, this time including the smaller hole as a detected feature, as shown in the following picture.

2FBM DrillFBM Drill is a feature-based machining (FBM) strategy that can detect holes in a solid and automatically generate a complete series of drill operations for the selected features. With FBM Drill you can:

Detect holes in a solid using specified criteria. Review the detected features list and edit or delete features. Preview toolpath operations and make additional changes before they are generated. Automatically generate a complete series of drill operations for the selected features.

In this lesson, you use FBM Drill to generate toolpaths to drill the holes indicated in the following picture.

Lesson Goals Generate FBM Drill toolpaths. Adjust feature detection. Customize FBM Drill toolpaths. Backplot the toolpaths. Verify the toolpaths.


Exercise 1: Creating the Drill Toolpaths1 If necessary, load the part file

FBMPartTutorial.SLDPRT that you saved at the end of the previous lesson.

Alternatively, you can start this lesson with the file FBMPart02.SLDPRT.

2 In the Mastercam X4 CommandManager, click FBM Drill.

The FBM Toolpaths - Drill dialog box displays.


FBM Drill analyzes the part and displays a set of operations for all detected holes, as shown in the following picture. Notice that the 20mm hole, which was toolpathed by FBM Mill in the previous lesson, is in the list.

FBM DRILL 85

4 Select the Hole Detection page.

5 Set the Minimum diameter and Maximum diameter settings to 0.5 and10.0, respectively.

Reducing Maximum diameter to 10 ensures that FBM Drill does not generate a toolpath for the 20mm hole.

6 Click the Detect button again.

FBM Drill uses the new parameters to reanalyze the part. The 20mm hole no longer appears in the feature list.

7 Click OK.

FBM Drill generates the drilling toolpaths and adds them to the mill toolpaths that FBM Mill generated in the previous lesson.
