CNC Machining Technology

The CNC MachiningTechnology program provides training that prepares students to set and operate manufacturing equipment, handle inspection devices, analyze production problems, and the potential to move into supervision of manufacturing. The program provides a balance between practical training in manufacturing processes and technical education in manufacturing analysis, planning, and control with supporting emphasis in communications, mathematics, science and business.  Students obtain a strong background in machining, engineering graphics, material handling and processing, computers (CADD/CAM, CIM, CNC), manufacturing analysis and planning, and leadership skills. To prepare for entry into the program courses in metal or wood shop, mechanical drawing, English, mathematics, physics, and computers are strongly recommended. Activity in clubs or organizations which emphasize leadership skills is also recommended. There is an opportunity for students to work in industry for a specified time and receive college credit, or to convert work and life experience into college credit for this program. Those interested in such an opportunity are encouraged to contact their advisor for further details at the time of registration. Students also have the opportunity to be involved in the program’s CNC Machining Club.

Robert McDonald, Professor

TOOL KIT

CNC Machining will require tools. Check out the link for the Tool Kit requirement.

JOB OUTLOOK

Quality control positions in manufacturing, millwright positions, machining positions, and fluid power industry positions are only some of the places in which employment can be found.

Positions may also be found in the following areas: CNC machining, computer systems for automated manufacturing, fabrication, and project development.

work setting

Job setting can be on the floor, working with production people and all related crafts in successfully coordinating applications and troubleshooting problems. Graduates are able to work directly with the engineer on projects in the plant.

APTITUDES

It is strongly recommended that stuents obtain English, mathematics, physics, mechanical drawing, a computer language, and club or organization leadership skills in high school.

wages

Wages vary with skill level, type of employment, geographic location, and job requirements. Beginning CNC Machinists typically start between $14.17 - 17.98 per hour. After 3-5 years of experience in the field, the bottom 10% makes less than $15.800 per hour while the top 10% makes over $37.860 per hour. The median wage is $50580 per year or $24.32 per hour.

ENTRANCE REQUIREMENTS

  • Enrollment priority is given to students on basis of student's advising date
