PROJECT #1: CNC MILLING OF A MOLD
This project involves the practice of designing a mold for injection molding
process to eventually produce a plastic part. The tools that will be used for the
project are:
TekSoft- ProCAM, CAD-CAM software
Hitachi-Seiki CNC Milling Machine
BOY Injection Molding Machine
CMM (Coordinate Measuring Machine)
The project constraints are as follows:
The mold will be machined out of a 4”x 4”x 3/8” plate of Aluminum 6061
At least 1/2" of clearance is required from the edges of the mold.
Maximum feature depth in the mold cannot exceed 1/8”.
Text is not allowed in the mold design.
Maximum simulated machining time allowed is 20 minutes.
Use of at least 3 different cutting tools is required for the milling
processes.
WHAT IS REQUIRED IN THE REPORT:
OBJECTIVE (5%)
One sentence.
INTRODUCTION (5%)
A summary of the report.
BACKGROUND (15%)
A general overview of the processes involved in the project, e.g. CAD/CAM,
CNC, Milling, injection molding etc. You are required to visit the Parks Library for
this section of the report.
PROCEDURE (25%)
Begin with the constraints. List the steps involved at each phase of the project.
Do not comment.
RESULTS (35 %)
State results of the procedures followed above. Remember, each phase of the
project has a goal, which defines the results. The results are required to contain:
list of layers, list of tools and depths of cut (designed and actual values), G-code,
simulated machining time, actual machining time, visual characteristics of the
mold and the part, injection molding process parameters and calculations. Do not
comment or explain.
DISCUSSION AND CONCLUSIONS (15%)
Comment on your results and on the outcome of the projects. Draw conclusions
and state them clearly.
