Course

32420348 Applied CNC-Operation and Setup
Course Information
Description
Through practical lab exercises and lectures, students develop the ability to establish work and tool offsets, verify part programs, and produce components that meet engineering specifications. Introduces CNC control interfaces, and common machining strategies. By the end of the course, students will be able to complete standard CNC setups, perform routine machine operation, identify machining errors, and make corrective adjustments to ensure part quality and production efficiency.
