Computer Aided Manufacturing (CAM)

• History of CNC

1949 US Air Force asks MIT to develop a "numerically controlled" machine.

1952 Prototype NC machine demonstrated (punched tape input)

1980- CNC machines (computer used to link directly to controller)

1990- DNC: external computer “drip feeds” control programmer to machine tool controller 

HOW TO LEARN CNC PROGRAMMING

 Description

The goal of this course is to teach persons with a technical background how to program and operate Computer Numerical Control (CNC) (HMC) mills and lathes.

To maximize learning, this course focuses on CNC machines made by Haas Automation.

• Haas Automation is the largest machine tool builder in the western world.

• Haas has donated or endowed many machines to colleges, universities, and technical schools, so they are likely to be found in educational institutes.

• All Haas machines use the same control, work similarly, and use industry standard programming. What is learned is easily transferred to other make or model machines.
• 
  
• Haas makes several small footprint CNC machines designed specifically for engineering,prototyping, medical, jewelry, and niche manufacturing industries

• CNC Cutting Tools      

1. End Mills
2. Face Mill
3. Corner Radius Tool
4. Slot Mill / Slotting Saw
5. Hole-Making Tool

• CNC Controller 

1. FANUC
2. HASS 
3. SIEMENS

• CNC AXIS 

       X-AXIS

       Y-AXIS

       Z-AXIS
