1.0.1 Laboratory - CNC Machining

[an error occurred while processing this directive]

 

Purpose:

The students will be introduced to the basics of CNC equipment.

 

Overview:

A simple tutorial will be used to introduce the students to the CNC equipment in the laboratory. The students will develop a simple G-code program to cut their initials on the mill and a candle stick on the lathe. Both programs can be simulated off-line, and then tested in the laboratory. You will also be introduced to automatic part programming software.

 

Pre-Lab:

1. Review the course material on CNC machines, and specifics for the PC-turn 50, and Pro-light machines.

2. Use netscape to explore the NC machines in the laboratory.

3. Develop by hand a program to cut your initials using the Pro-light NC mill. The initials will be cut on a 2” square piece of aluminum. Correct speeds and feed should have also been determined.

4. Develop by hand a program to cut a candlestick in brass with a 1” dia on the PC-turn 50 lathe. Correct speeds and feed should have also been determined.

5. Simulate both programs before arriving at the laboratory.

 

In-Lab:

1. In the lab you will be shown how to set up the NC lathe and mill, fixture parts, and set the origin.

2. You will then individually enter and manufacture your parts.

3. Learn how to use MasterCAM, SmartCAM, or ProEngineer to produce NC code. Tutorial manuals will be provided in the lab.

 

Submit:

1. Part programs for both parts.

2. Digital photographs of both parts.

3. A simple part program generated on the software of your choice.
