INTRODUCTION “WHAT IS “MASTERCAM“?

Mastercam® is the world’s most widely-used CAM software from CNC Software, Inc

Machine tool programmers can program parts graphically in Mastercam, using the innovative, time tested,proven toolpaths and machining strategies preferred the most by shops around the world This book is astep-by-step “hands-on” book of examples to have you programming quickly without knowing NC Machineprogramming languages

WHO THIS BOOK IS FOR:

This book is for the machine tool programming student who wants to learn how to program 3D model partsusing Mastercam

This book covers Mastercam Mill (3D toolpaths) and assumes you already are able to draw and to machine2D model parts using Mastercam programming This book also assumes that the student using this book isfamiliar with machining processes, tools and how Numerical Control (NC) machines operate This book isintended to teach you how to get your job done using Mastercam

PROGRAMMING TECHNIQUES USED IN EXAMPLES:

The example exercises in this book can be programmed an infinite number of ways In fact, any two

programmers 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 options thatcan be set or changed to suit your experiences or company standards

We chose some time different methods to compare the toolpaths Utilize the Mastercam Help that is

accessible from most dialog boxes whenever you need more information about options

Getting Started The Mastercam® User Interface

THE MASTERCAM® USER INTERFACE

Mastercam is a completely graphic programming interface that includes built in CAD tools You will find theinterface to be very streamlined and easy to access all of the toolpath generating commands There areseveral places you need to know to access all of the Mastercam commands The locations for the Mastercamcommands and tools are shown in the screen display below

Getting Started Attributes, Groups And Mini Toolbar

ATTRIBUTES, GROUPS AND MINI TOOLBAR

The Home tab Attributes and Organize groups or the Mini Toolbar allows you to set the attributes (color, level,

style and width) and Z depth currently used.

TheHometab with the

AttributesandOrganize

groups should look as shown

Example of the defaultMini Toolbar

Point Style Sets the display of points The box or circle point styles are especially useful

when working with 3D Drawings.

Line Style Line style, such as solid, hidden, or phantom

Line Width Line width and surface UV line width.

Wireframe, Solids & Surface Color

You can choose to set or change the Wireframe color, the Solids color and the Surface color Colors help organize and simplify the drawing Up to 256 colors are available Select from the color dialog box by clicking on the colored area The number inside the box represents the color palette number.

Clear Colors

Removes the group and result colors from affected entities and from the database When performing a transform function, Mastercam creates a temporary group from the originals (red) and a result (purple) group from the transformed entities However, the groups stay in effect only until you use the Screen, Clear Colors function or perform another transform function.

Select All Changes multiple attributes.

Set from entity Allows you to select an existing entity and sets the current attributes based

on the entity attributes.

2D/3D Mode 2D or 3D drawing mode Determines whether Z-inputs are from the

Working Depth field or from mouse

Change Level Change the level of the selected entities.

Set Material Displays and sets the material for selected objects.

Example Of Setting The Current Wireframe Color

n First, make sure that no entities are selected in

the graphics window

n Right mouse click to open theMini Toolbarand

click on the drop down arrow next to the

Wireframecolor as shown

n Select the desired color from the dialog box as shown

Note: Any geometry on your screen will remain in the previous system

color This change will only affect the geometry you create going forward

Example Of Changing The Current Wireframe Color

n To change the color or any other attribute of a

pre-existing entity you first need to select the entities that

have to be changed

n Right mouse click to open theMini Toolbarand click on

the drop down arrow next to theWireframecolor as

shown

Getting Started Data Entry Shortcuts

n Select the desired color from the dialog box as shown

DATA ENTRY SHORTCUTS

Mastercam lets you use several shortcuts to enter information into text boxes when creating geometry.These shortcuts let you get data from an existing entity and use it when creating new geometry

The shortcuts are as follows:

D Use "D" to input an existing diameter

L Use "L" to input an existing line length.

R Use "R" to input an existing radius.

S Use "S" to input the distance between two existing points.

X Use "X" to input an existing X coordinate.

Y Use "Y" to input an existing Y coordinate.

Z Use "Z" to input an existing Z coordinate

To Use A Shortcut

n Type a letter (from the list above) instead of a value into the text box

n PressEnter Mastercam prompts you to select the existing entity from which you want to get the data

n Select the entity you want to use

n Mastercam displays the data it gets from the existing entity

n PressEnterto accept the data Type a different value and pressEnter

n Mastercam uses the data from the existing entity in creating the new entity

Data Entry Shortcut Example

This example uses the "L" data entry shortcut to create a line

Create a line withEndpointsof0,0,0and3,0,0

This will be the existing line from which you get data by using "L"

n Select theWireframetab and click on theLine Endpointsicon

n Select theOriginas the first lineEndpoint

n Set45as the angle of the line and pressEnter

n Type "L" to activate theLengthfield and then highlight the existing value and type "L" in the field andpressEnteragain

n Mastercam prompts you to select an existing line

n Select the existing line

THE RIGHT MOUSE CLICK MENU

Zoom Window

Gview Allows you to set the graphics view from Back, Left, Bottom, Isometric Reverse or

Trimetric.

Delete Entities Erases the selected entities.

Analyze Distances Analyzes the distance between two points.

Analyze Entity Analyzes and allows you to edit selected entity lengths, angles, positions and attributes.

Getting Started AutoCursor

AUTOCURSOR

Allows the user to select Endpoints, Midpoints, Arc Center Points or various other entity points

Mastercam prompts you to enter a point To select a point move the cursor over the geometry on the

screen A little square will appear on the screen and a corresponding cursor icon will be displayed

AutoCursoroptions are available each time Mastercam prompts you to enter a point You can select tooverride theAutoCursoror to set the defaults from theGeneral Selection Bar

Note: You can set the AutoCursor defaults This will determine which entities are shown when your

cursor hovers near by

Getting Started Planes & The Coordinate Systems

PLANES & THE COORDINATE SYSTEMS

Mastercam uses a 3D Cartesian coordinate system to locate your work in three-dimensional space Thismeans that geometry and toolpath positions are expressed in terms of three coordinate axes - X, Y, and Z.Each axis is signed, which means that it has a positive and a negative direction

The main tool for applying coordinate systems in Mastercam is the plane A plane consists of two mainparts: a slice through the coordinate system and an origin, or zero point

TheConstruction Plane (Cplane)is the plane in which new geometry is created

TheTool Plane (Tplane)is the cutting plane for a toolpath, typically normal to the tool axis

TheWork Coordinate System (WCS)lets you move the coordinate system to your part geometry instead ofmoving or transforming the part geometry Think of theWCSview as defining the "Top plane" relative toyour part

There are 9 standard Graphics Views or Planes in Mastercam

MASTERCAM® PARAMETER DIALOG BOXES

When you begin creating toolpaths with Mastercam® you will be required to supply information so you cancreate the toolpath exactly the way you want it Mastercam® utilizes a tree-style dialog box interface that ismade up of several distinct areas as shown

Tree View Area Displays a list of all of the available dialog box pages.

Page View Area Changes with each new Tree Menu item selected Each page has selections

to be made.

Quick View Settings Area Shows a quick summary of key selections you have made on various pages.

Confirmation Area Area to Accept and Close, Cancel, Apply or get Help about the displayed

page.
