CNC Prototype Machinist

We are seeking an experienced CNC Prototype Machinist to join our machine shop team. Under general supervision, develops, writes, and edits programs that direct automated machine tools to cut and shape precision metal parts, tools, and products.  Additionally, sets up and operates CNC and manual machining equipment to product prototype components and precision parts.  Uses blueprints, CAD data, and engineering sketches to ensure all specifications, dimensions, and tolerances are met.  Works closely with engineers and production staff to refine designs for manufacturability, accuracy, and efficiency in prototype and limited-run production environments.

Key Responsibilities

• Analyze job orders, blueprints, CAD data, and engineering documentation to determine machining operations, sequences, and dimensions.
• Write, test, and revise CNC programs to control machining or processing of metal or plastic parts.
• Select and set up appropriate tooling, fixtures, and machining parameters such as cutting speeds, feed rates, and depths of cut.
• Operate CNC and manual machine tools (vertical mills, horizontals, lathes, grinders, etc.) to fabricate prototype and production components.
• Review and interpret blueprints, CAD models, and specifications to ensure compliance with dimensional and tolerance requirements.
• Calculate dimensions and tolerances using precision instruments such as micrometers, calipers, and height gauges.
• Inspect finished products to verify accuracy and quality using precision measuring tools and visual inspection techniques.
• Perform setups, adjustments, and minor maintenance on machinery as needed to maintain accuracy and efficiency.
• Simulate or test programs to ensure that machinery functions properly and meets engineering requirements.
• Prepare setup sheets, documentation, and process notes for repeatability and training.
• Collaborate closely with engineers, machinists, and production staff to optimize prototype manufacturability and machining processes.
• Maintain knowledge of evolving CNC control systems, programming languages, and machining technology.
• Train or provide technical guidance to machinist and operators as needed.
