CNC Milling Programmer

The CNC Milling Programmer is responsible for programming, setting up, proving out, and machining very small, high-precision components where accuracy, repeatability, and attention to detail are critical.

The ideal candidate will have strong hands-on experience with Mastercam CNC programming, precision milling, work holding and fixturing, and the ability to independently take a component from engineering drawing through programming, setup, prove-out, and production.

Because many of the components produced are extremely small and contain intricate features, this position requires a strong understanding of tool geometry, cutter selection, feeds and speeds, tool deflection, burr control, chip evacuation, and process stability. Experience working to demanding aerospace quality requirements and tight dimensional tolerances is highly desirable.

• Create, modify, and optimize CNC milling programs using Mastercam for precision aerospace components.
• Program complex and highly detailed parts, including components with small features, tight tolerances, thin walls, deep pockets, small holes, and intricate geometries.
• Develop efficient machining strategies while maintaining dimensional accuracy, surface finish, tool life, and repeatability.
• Review engineering drawings, CAD models, specifications, and manufacturing requirements prior to programming.
• Read and accurately interpret engineering drawings, blueprints, GD&T, tolerances, and material specifications.
• Utilize Solid Works and CAD models to support programming, process development, and manufacturing.
• Create complete and accurate setup sheets, including tooling, work offsets, tool numbers, tool lengths, machining sequence, inspection requirements, and other relevant setup information.
• Determine appropriate tooling, cutters, feeds and speeds, cutting strategies, and machining parameters based on material, geometry, tolerances, and feature size.
• Develop and implement effective work holding and fixturing solutions, including proper use of Kurt vises, soft jaws, parallels, custom fixtures, and other precision work holding methods.
• Program and utilize KOMA 4th Axis Plus indexer rotary machining for multi-sided and complex components.
• Set up, prove out, and independently operate CNC milling machines from first-piece setup through production.
• Perform program prove-outs and make necessary adjustments to ensure safe, efficient, and accurate machining.
• Optimize existing CNC programs to improve cycle time, tool life, surface finish, and overall process reliability.
• Troubleshoot machining problems such as tool deflection, chatter, burr formation, poor surface finish, dimensional variation, tool wear, work holding issues, and inconsistent repeatability.
• Understand the unique challenges associated with machining very small precision components, including maintaining part stability and controlling cutting forces and tool deflection.
• Make appropriate program and process adjustments based on in-process inspection and first-piece results.
• Work closely with machinists, quality personnel, engineers, and manufacturing personnel to resolve production and quality issues.
• Support the development of repeatable and robust manufacturing processes for new and existing aerospace components.
• Maintain accurate documentation and ensure programs and setup information are organized and readily available for production.
• Follow all applicable company procedures and aerospace manufacturing requirements related to quality, traceability, documentation, and process control.
• Maintain a clean, organized, and safe work environment.
• Consistently meet production schedules while maintaining the required level of quality and precision.
• Consistently demonstrate Ausco’s 30 Specifications values,…
