CNC Programmer / Technician

Job Title: CNC Programmer / Technician

Department: Manufacturing Engineering

Reports To: Sr. Manufacturing Engineer

FLSA Status: Non-Exempt

SUMMARY

The CNC Programmer / Technician is responsible for independently developing and executing machining processes for complex precision components from engineering documentation through production release.

This is a hands-on position supporting CNC milling, turning, Swiss, and multi-axis millturn equipment in a precision manufacturing environment.

ESSENTIAL DUTIES AND RESPONSIBILITIES include the following. Other duties may be assigned.

Programming & Process Planning

• Develop CNC programs using advanced CAM software.
• Program 2 and 3-axis turning operations with live tooling, 3, 4 and 5-axis milling operations, and up to 10-axis mill-turn and Swiss style operations.
• Establish operation sequence and toolpath strategies based on component geometry, material, tolerance requirements, and machine capability.
• Read and modify G-code, including macros, variables, subprograms, and machine-specific functions.
• Verify programs for collisions, interference, and machine travel limitations.

Machine Setup & Prove-Out

• Perform machine setups and first-run prove-outs for new components.
• Establish work coordinate systems, tool offsets, and required machine configurations.
• Safely execute new programs while evaluating machine movement and cutting conditions.
• Make necessary adjustments during prove-out and establish repeatable production processes.

Cutting Tools & Workholding

• Select cutting tools, inserts, toolholders, feeds, speeds, depths of cut, and engagement parameters appropriate for each application.
• Determine workholding methods that provide the required rigidity, accessibility, repeatability, and part location.
• Design and manufacture soft jaws, fixture components, subplates, stops, and other custom workholding solutions.

Process Optimization

• Improve established processes to reduce cycle time, extend tool life, improve surface finish, and increase process stability.
• Develop unattended and lights-out machining applications using technologies such as probing, redundant tooling, tool-life management, bar feeding, part unloading, and pallet systems where applicable.
• Evaluate new machining techniques and technologies for practical shop-floor application.

Troubleshooting

• Diagnose machining problems involving dimensional variation, chatter, deflection, distortion, chip control, premature tool wear, and unexpected machine behavior.
• Troubleshoot machine alarms and control-related issues.
• Determine root causes and implement corrective actions to restore reliable production.

Inspection

• Interpret engineering drawings, GD&T, specifications, and dimensional requirements.
• Perform first-piece and in-process inspection using precision measuring equipment.
• Monitor dimensional results and make corrections as necessary to maintain tolerance.

Technical Training

• Provide technical guidance to shop personnel.
• Train less-experienced personnel in proper machining practices, safe equipment operation, and preventative maintenance.
