CNC Milling and Turning Setup Programmer (Computer Numerical Control Milling and Turning Setup Progr
Computer Numerically Controlled Tool ProgrammersDescription
Program, set up, and prove out CNC milling and turning operations to machine parts to specification. Create and optimize G-code/CAM toolpaths, select tooling and workholding, set offsets, and ensure safe, efficient production; may operate machines for first articles and perform minor maintenance.
- • Develop CNC programs for vertical/horizontal mills and CNC lathes to meet print and GD&T requirements.
- • Define process sequence; select cutters, inserts, holders, and workholding for both milling and turning.
- • Review job orders, CAD models, and blueprints to set dimensions, tolerances, speeds/feeds, and stepovers.
- • Establish datums and work coordinate systems (e.g., G54-G59); set tool length and diameter compensation.
- • Create toolpaths in CAM and/or hand-code G/M-code; post-process for specific machine/controllers.
- • Simulate toolpaths, verify collisions/clearances, and run first-article prove-outs on the machine.
- • Inspect first articles; compare results to prints/CAD and adjust programs or offsets as needed.
- • Edit and debug programs at the control; eliminate alarms, chatter, gouges, and scallops.
- • Optimize cycles by refining rough/finish strategies, depths of cut, stepovers, and tool engagement.
- • Generate setup sheets, tool lists, probing cycles, and part zero instructions for operators.
- • Design or specify soft jaws, fixtures, and clamps; model fixtures in CAD to support programming.
- • Program turning cycles (facing, OD/ID turning, threading, grooving) and live-tool milling when required.
- • Transfer and manage programs via DNC/network; maintain revision control and backups.
- • Standardize tooling and group jobs to reduce changeovers and maximize spindle uptime.
- • Perform basic preventive maintenance, tool presetting, and report machine or tooling issues.
