Title: Precision Machining Technology A.A.S.
(Associate of Applied Science Degree)
Degree Plan Code: AAS.MT.PREC.MACH
- Students pursuing this award program are required to meet Texas Success Initiative (TSI) standards and course prerequisites.
- Complete at least 25% of the credit hours required for graduation through instruction by Dallas College.
Computer Numerical Control (CNC) Machinists and Technicians require a broad mix of hands-on metal working skills and computer skills combined with Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) software systems.
This program covers blueprint reading, Geometric Dimensioning and Tolerancing (GD&T), manufacturing process planning, CAD/CAM Solid Part Modeling and Numerical Control (N/C) Programming, precision machining (both manual and CNC machines) and inspection, shop math, and quality control. Knowledge is acquired and skills are developed through textbook, online curriculum, and hands-on lab assignments. Lab work includes the use of CAD/CAM software and state-of-the-art manufacturing equipment to produce machined parts from raw metal stock, according to blueprint specifications.
This program prepares students for the following jobs:
- Skilled Manual Machinist
- CNC Machinist
