Description
Develop, test, and optimize numerical control programs for machine tools and manufacturing systems to machine or process materials; may also assist with setup, operation, or basic maintenance.
- • Determine machining sequences and select cutters, holders, and tooling to produce required features.
- • Analyze job orders, drawings, blueprints, CAD models, and specifications to calculate dimensions, speeds, and feeds.
- • Define datum references, toolpaths, and hole locations; compute linear and angular dimensions, radii, and curves.
- • Write, post-process, and format programs in machine controller languages (e.g., G-code/M-code).
- • Simulate and verify programs or conduct trial runs to ensure functionality and conformance.
- • Debug and revise programs to eliminate errors; retest until issues are resolved.
- • Modify existing programs to improve cycle time, surface finish, and tool life.
- • Compare program output and sample parts to original specifications and blueprints to verify accuracy.
- • Enter and manage coordinates, offsets, and parameters in controllers or CAM systems.
- • Store, retrieve, and transfer part programs and graphics via DNC or data management systems.
- • Prepare geometric layouts, fixtures, and workholding in CAD/CAM to support programming.
- • Create setup sheets, tool lists, and work instructions for machine setup and operation.
- • Group and schedule jobs to maximize material utilization and minimize setups and changeovers.
- • Perform preventive maintenance checks and minor repairs on programming-related equipment or machines.
- • Collaborate with machinists, engineers, and quality teams to resolve issues and implement process improvements.
