You will learn how to use the Classic Tool Manager to create new tools and save them into a new library.You will also create tools by importing their STEP geometry from a tool manufacturer

The difference between the two types of Dynamic High Speed Machining: Dynamic Mill Radial Chip

Thinning (RCT) and Dynamic Motion Power Cutting with be explained in detail

You will learn how to program Horizontal centers which are better suited for larger, boxy workpieces

Mastercam uses the planes to machine a part on a Horizontal Machining Center and to determine the tableindexing angles

A brief introduction to the basic 3D machining that can be used in a Mill product will be also covered You willlearn how to alter the wireframe to generate one surface using Revolve and Loft/Ruled surfaces

Solids manipulations using Model Prep functions is also covered You will use Split Solid Faces command tosplit a solid face using Project and Flowlines options The student will learn how to use Push/Pull command

to change the height of the split areas You will be using Move command to rotate parts of the solid

You will also learn how to add an inner shoulder using Push/Pull command The student will also use

Push/Pull command to create fillets

You will learn how to set a solid body, that represents the part to be machined, into the fixtures using Align toPlane and Align to Face

An introduction to Nesting in Mastercam that allows you to fit parts onto a sheet of material for best yield willalso be provided You will learn how to apply the nesting options on geometry or toolpaths

A more in depth description of the Toolpaths Manager panel is provided in this book A detailed explanation

of the Toolpath Manager Control dialog box and of its right mouse menu is also included

PROGRAMMING TECHNIQUES USED IN EXAMPLES:

The example exercises in this book can be programmed in an infinite number of ways In fact, any twoprogrammers would likely approach each part a different way and probably use different tools or toolpaths.For the exercises in this book, we used settings that were the personal preference or that came from theexperience of multiple Mastercam authorized instructors All of the examples and exercises have optionsthat can be set or changed to suit your experiences or company standards

We chose one method rather than clutter the book with all of the possible options and disrupting the

workflow of the exercises Utilize the Mastercam Help that is accessible from most dialog boxes wheneveryou need more information about options

Configuration Backup & Restore

In this lesson you will learn how to backup the System Configuration files that contain all the information

about your Mastercam Attributes such as Colors and Line width, as well as the interface Background color

that you want to use In the System Configuration dialog box, you can also review and set Mastercam

start up default values

Mastercam settings are stored in a configuration file (*.config), which typically resides in a CONFIG

directory under the main Mastercam directory When you restart Mastercam or initialize operations (forexample, open a new file), Mastercam restores the default settings that have been saved in the Mastercamconfiguration file

There are two standard configuration files one for inch and one for metric units

Another important file that needs to be backed up is the Workspace file, Mastercam.Workspace, which

contains all the information about the interface such as your custom Ribbon bars You can have multipleconfiguration files but only one Workspace file The keymap information about your shortcuts key to navigateMastercam is also stored here

To summarize:

n You will learn how to backup and restore the config file

n You will learn how to backup and restore the workspace file
