PROJECT 4
CRIBBAGE BOARD PROJECT
Mill Level 1 ! Contour, Pocket & Drill
PROJECT WORKBOOK CRIBBAGE
Objectives
The student will design a Cribbage Board, then create a toolpath to machine the Cribbage Board on a
CNC machine. This tutorial covers the following topics:
Navigate the Mastercam menus
Create lines, arcs, points and letters
Translating and offsetting lines
Entering coordinates
Constructing 3 dimensional geometry
Chaining methods
Contour, drill and pocket toolpaths
Parameters for a contour, drill and pocket toolpath
Verify the toolpath in Verify
Posting the NC file
Customizing the toolbars
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.
Toolpaths/Solids Manager to the left of the screen can be hidden to gain more space in the graphic area
for design. Press Alt + O to remove it.
Before starting the geometry make sure that the Grid is enabled. It will show you where the part origin is
located. See Getting started page A!5 for details.
