CNC Machinist

CNC Machinist

The CNC Machinist is a key member of the manufacturing team, responsible for setting up/programming, operating, and maintaining CNC machines to produce precision components and parts. This role requires a skilled operator with expertise in programming, tooling, and machining techniques specific to HAAS equipment. The CNC Machinist will interpret engineering drawings, blueprints, and CAD/CAM models to generate machining programs, select appropriate cutting tools and fixtures, and optimize machining parameters for efficient production.

Responsibilities also include monitoring machining processes, conducting quality inspections, and making adjustments as needed to ensure accurate dimensions and surface finishes. The ideal candidate will possess strong technical skills, including proficiency in HAAS machine operations, along with a commitment to safety, quality, and continuous improvement in manufacturing operations. Effective communication and teamwork are essential for collaborating with colleagues to meet production targets and deliver high-quality machined components to customers.

Essential Functions

• Machine Setup : Prepare CNC machines, including HAAS machinery, for operation by loading programs, setting up cutting tools, fixtures, and workpieces, and ensuring proper alignment and calibration
• Programming : Generate CNC machining programs using CAM (Computer-Aided Manufacturing) software based on engineering drawings, blueprints, and CAD/CAM models, ensuring accuracy and efficiency in machining operations
• Tooling Selection : Select appropriate cutting tools, inserts, and tool holders based on machining requirements, material properties, and tool life considerations, optimizing tooling setups for each job
• Machine Operation : Operate CNC machines to perform machining operations such as milling, turning, drilling, and threading, monitoring machine performance, tool wear, and surface finishes to maintain quality and productivity
• Quality Control : Inspect machined parts using precision measuring instruments such as micrometers, calipers, gauges, and CMM (Coordinate Measuring Machine) equipment, verifying dimensions, tolerances, and surface finishes to meet quality standards
• Troubleshooting : Identify and troubleshoot machining issues, tooling problems, and programming errors during production, making adjustments or modifications as necessary to ensure optimal performance and quality
• Maintenance : Perform routine maintenance tasks on CNC machines, including cleaning, lubricating, and replacing worn or damaged components, to prevent breakdowns and ensure reliable operation
• Safety Compliance : Adhere to safety protocols and guidelines while operating CNC machinery, including wearing appropriate personal protective equipment (PPE) and following safe work practices to prevent accidents or injuries
• Documentation : Maintain accurate records of production activities, including machining programs, setup sheets, tooling changes, inspection results, and production quantities, to track productivity and ensure traceability
• Communication : Communicate effectively with supervisors, programmers, engineers, and other team members to coordinate workflow, troubleshoot issues, and provide feedback for process improvement
• Continuous Improvement : Identify opportunities for process optimization, cycle time reduction, and waste elimination in CNC machining operations, contributing to overall operational efficiency and quality improvement initiatives
