TUTORIAL #31
TUTORIAL #3
Objectives:
The Student will design a 2-dimensional drawing by:
!Create arcs polar knowing the diameter, location, start and end angles.
!Create parallel lines, by defining the offset direction and distance.
!Create fillets knowing the radius size.
!Create lines on an angle knowing the starting point and angle.
!Mirror the part to create the other 1/2 of the part.
The Student will create toolpaths consisting of two setups:
!An open pocket toolpath to remove the material in the open area.
!Contour remachining toolpath to cut the material which the open pocket left.
!A circle mill toolpath to remove the material in the arc.
!Three drill toolpaths to, spot drill, drill and tap the holes.
!A contour toolpath to remove the material at the parts exterior.
!The contour toolpath will be part of setup #2
The Student will simulate the toolpaths using Mastercam's Verify and Backplot by:
!Defining a 3-dimensional rectangular block the size of the workpiece.
!Running the Backplot to see the path the tool takes to cut the part.
!Running the Verify to simulate the tool cutting from a solid model.
This tutorial takes approximately one hour to complete.

SETTING UP THE GRAPHIC USER INTERFACE TUTORIAL #31
GEOMETRY CREATION
STEP 1: SETTING UP THE GRAPHIC USER INTERFACE
Before starting the geometry creation we should customize the toolbars to see the toolbars required
to create the geometry and machine a 2D part. See Getting started page A-4 for details.
Make sure that the Grid is enabled. It will show you where the part origin is. See Getting started page
A-6 for further information.
The Operations Manager to the left of the screen can be hidden to gain more space in the graphic area
for design. From the keyboard, press Alt + O keys simultaneously to hide it. Repeat this command to
make it visible again.

TUTORIAL #31 SELECT THE MACHINE AND SET UP THE STOCK.
STEP 13: SELECT THE MACHINE AND SET UP THE STOCK.
In Mastercam, you select a Machine Definition before creating any toolpaths. The Machine Definition
is a model of your machines capabilities and features. It acts like a template for setting up your
machine. The machine definition ties together three main components. The schematic model of your
machines components. The control definition that models your control capabilities and the post
processor that will generate the required machine code (G-code). For a Mill Level 1 exercise (2D
toolpaths) we need just a basic machine definition.
To display the Operations Manager press Alt + O.

CIRCLE MILL THE LARGE HOLE TUTORIAL #31
STEP 18: CIRCLE MILL THE LARGE HOLE
Circle mill toolpath is used to mill circular pockets based on a single point. Mastercam will pocket out a
circular area of the diameter and to the depth that you specify. After milling the center of the circle,
Mastercam calculates an entry arc before approaching the perimeter and then a similar exit arc. You
can add enhancements such as multiple passes, multiple depth cuts and helical plunge moves as well
fine tuning the entry and exit arcs.

CREATING AND RENAMING TOOLPATH GROUPS TUTORIAL #31
STEP 22: CREATING AND RENAMING TOOLPATH GROUPS
To machine the part in two different setups, we will need to have two separate programs. To be able
to post process separately the operations of each setup, we will create them under different toolpath
groups with different NC names.
22.1 Rename the current Toolpath Group - 1 and NC file
Click two times on the Toolpath Group - 1 to highlight it and rename it "Setup #1."
