Machining Technology

Computer Numerical Control Operators use a complete CNC program to operate a CNC machine. They download the completed program into a CNC machine controller, make sure the program is correct, load the stock material, and operate the machine. Computer Numerical Control operators check the completed part for accuracy and quality assurance.

Computer Numerical Control Programmers use engineered drawings and computer software to accurately create a three-dimensional model of the machine part. The 3D model is created in software such as Mastercam. CNC programmers create tool paths, program cut speeds, and program different types of tooling needed to cut out the part. Once all steps have been followed, the CNC programmer saves the completed file for use on CNC equipment. CNC programmers can also write the CNC code manually, line by line.

Manual machinists use engineered drawings to machine various type of industrial, medical, and commercial parts. They use lathes, mills, saws, and grinders to cut, drill, and smooth out machined parts. Manual machinists use various types of rulers, scales, and measuring tools to check their machine parts for accuracy and quality assurance.

The sheet metal courses will provide students with an introduction to the materials, tools and techniques used in the sheet metal industry as well as types and uses of hand, layout, and cutting tools along with bending and forming machines. Students will learn about various types of pipe and fittings, principles of soldering roof flashings, gutters, down spouts, and sheet metal duct fabrications. Emphasis on principles and type of fittings for radial line development are discussed and factors that influence bend allowances and calculations necessary for determining proper bend allowances.
