Tutorial 1: Machining a Gasket
Using 2 �½ Axis Profiling
10
Introduction
This tutorial will illustrate machining of a simple prismatic part such as this gasket using 2-1/2
milling operations. Even though we have created a 3-D representation of the gasket, it will be
seen later on that we can machine this using just 2-D curves (sketches).
The reason we are able to do this is because of the prismatic nature of this model.
The stepped instructions are accompanied by explanatory and introductory text. Reading this
text will help you understand the tutorial methodology and provide information about additional
options available.
Don’t forget to save your work periodically! You may want to save the file under a different
name so that the original file will be preserved.
Strategy to Machine the Gasket
•
•
•
We will machine the Gasket by using a 2-�½ axis machining operation called Profiling.
The part will be machined out of a 8 �½ x 5 x ¼ inch poplar wood sheet using a �½ inch
Flat End Mill.
The wooden sheet will be held to the machine table or the spoil sheet on the table using
double-sided tape.
Main Programming Steps
In creating programs for each setup, the following steps will be followed:
•
•
•
•
•
•
•
•
•
Create the Stock geometry
Set the Machine zero point or Locate geometry with respect to the machine coordinates
Create / Select the tool used for machining
Set the feeds and speeds
Set the clearance plane for the non-cutting transfer moves of the cutter
Select the machining regions for containing the cutter to specific areas to cut
Select the machining operations and set the parameters
Generate the toolpath
Simulate the toolpath.
You may have to repeat either all or part of these steps for subsequent operations.
Loading the Part Model
Use the Alibre Design menu bar or the Standard toolbar buttons to create, load and save part
geometry.
New Part:
Creates a new part. Though you can create your part with any units, Alibre CAM
only accepts parts for which the units are in Inches or Millimeters. You can easily switch to
these units when necessary by going to File > Properties > Units and selecting the applicable
item under the Display Units section.
Open:
Loads Alibre Design parts or assemblies
Import:
Imports files created outside of Alibre Design.
Save:
Saves the current file.

Getting Started with Alibre CAM
1. Select File / Open Part, or click the Open Part icon from the Alibre Design standard
toolbar.
2. From the
Open
dialog box, select the
Gasket.AD_PRT
file from the
Tutorials
folder in
the Alibre CAM installation folder. (Default location C:\Program Files\MecSoft
Corporation\Alibre CAM 2.0\Tutorials)

3. The loaded part appears as shown below.
Note:
You must work in shaded mode in order to be able to visualize toolpaths created in
Alibre CAM. It is suggested for best visual performance with Alibre CAM to work with only
one view port open and the view port operating in shaded mode.
Loading the Alibre CAM Browser
1. Select Alibre CAM from the menu bar and click Machining Operations Browser.

Getting Started with Alibre CAM
The Alibre CAM browser (MOPs and Cutting Tools) is now loaded and is docked over the
Design Explorer. You can toggle between the MOPs browser and the Design Explorer from
the tabs at the bottom of the window. It can be hidden by un-checking Browser on the
Alibre CAM menu bar. To re-display the hidden Browser window, you can re-check
Browser
from the Alibre CAM menu entry. You can also resize it by dragging one of its sides.
Preparing the Part for Machining
The Setup tab allows the user to specify Machine Setup, Select Post Processor, Stock Geometry,
Machine Coordinate System (Machine Zero) & Preferences.
Setup Machine
1. Click on the Setup tab located under the MOPs Browser and select Setup Machine
