CNC Operator/Programmer

Walker Products

Location: Fruita, CO

Primary responsibilities

• Create, edit, and optimize CNC programs for new and existing components.


• Perform complete machine setups, including tooling, workholding, offsets, and program verification.


• Interpret engineering drawings, GD&T, specifications, and manufacturing requirements.


• Prove out new programs and establish repeatable machining processes.


• Troubleshoot dimensional, tooling, machine, and process-related issues.


• Perform first-piece and in-process inspection using appropriate measuring equipment.


• Adjust programs, speeds, feeds, tooling, and machining strategies to improve cycle time and tool life.


• Document setup information so processes can be reliably repeated by production personnel.


• Support transition of completed setups into normal production.

Machines and controls used

• Experience programming and setting up CNC equipment such as Swiss-style lathes, CNC turning centers, CNC mills, multi-axis equipment, or screw-machine replacement applications, depending on Walker's equipment mix.


• Tsugami B0-205's / B0-206's; S-206's


• Citizen Swiss capability


• Live tooling / sub-spindle experience

Programming software used

• Espirit, Bobcad, Mastercam


• Ability to program at the control when required


• Understanding of G-code and M-code


• Ability to troubleshoot and edit existing programs without having to completely reprogram a job

Programming expectations

• Must have demonstrated ability to independently develop CNC programs and machining processes from engineering drawings, including tooling selection, workholding strategy, speeds and feeds, operation sequence, and inspection requirements.

Parts, Materials & Tolerances

• Stainless steels, carbon/alloy steels, aluminum, brass, and other applicable materials


• Small, precision-machined components


• Tight-tolerance production machining


• Ability to hold dimensional requirements of ±0.0005 in. or tighter where required, if that reflects your actual work


• Working knowledge of surface-finish requirements


• GD&T interpretation and application

Additional duties

• Identify opportunities to reduce cycle time, setup time, scrap, and tooling cost.


• Develop standardized setup documentation.


• Assist in fixture and workholding development.


• Improve process capability and repeatability.


• Support root-cause analysis of machining and quality problems.


• Assist with new-product introduction and first-article activities.


• Train CNC operators on established processes and setup requirements.


• Work collaboratively with Engineering, Quality, Production, and Maintenance.


• Support continuous-improvement activities involving tooling, machine utilization, capacity, and manufacturing efficiency.
