Job description

As a CNC Machinist, you will set up, operate, and optimize CNC milling equipment in a 3- to 5-axis machine shop, producing high-precision components to tight tolerances. You will interpret blueprints and GD&T requirements, adjust machining parameters, and verify part quality using a range of precision measuring tools, contributing directly to the accuracy and reliability of finished parts.

Responsibilities

• Review blueprints, drawings, specifications, and sample parts to determine machining requirements and the optimal sequence of operations.
• Set up and operate CNC milling machines, including 3- to 5-axis equipment, to produce high-precision components.
• Select and install appropriate tooling, inserts, fixtures, boring bars, and other workholding devices required for each job.
• Set and adjust speeds, feeds, tool offsets, and work offsets to maintain machining accuracy and surface finish quality.
• Read, interpret, and make edits to FANUC G-code programs to optimize machining processes and resolve issues at the machine.
• Use Mastercam or similar CAM software experience (where applicable) to support programming and process improvements.
• Inspect finished parts to ensure they meet customer specifications and tight tolerances using micrometers, verniers, bore gauges, height gauges, thread gauges, calipers, and other precision measuring equipment.
• Interpret blueprints and GD&T requirements to confirm dimensional accuracy and feature relationships.
• Complete First Article Inspections (FAI) in accordance with AS9102 standards and document results accurately.
• Perform machine setups, including zeroing workpieces, aligning fixtures, and verifying tool lengths and diameters.
• Monitor machines during operation, identify abnormalities such as tool wear or vibration, and make appropriate adjustments.
• Maintain a clean, organized, and safe work area in and around CNC mills, lathes, and related equipment.
• Collaborate with team members, programmers, and supervisors to troubleshoot machining challenges and improve processes.
• Handle vertical milling operations and work with equipment such as Haas and Mazak machines as required.
• Follow established quality procedures and shop practices to ensure consistent, repeatable production results.
• 3–5+ years of CNC machining experience in a production or job-shop environment.
• Hands-on experience setting up and operating CNC milling machines, including 3- to 5-axis mills.
• Proficiency in reading and interpreting blueprints, drawings, and schematics.
• Strong working knowledge of GD&T (Geometric Dimensioning and Tolerancing).
• Ability to read, interpret, and edit FANUC G-code programs at the machine control.
• Experience with CNC machine setup, including tooling selection, fixture setup, and work offset setting.
• Proficiency using precision measuring tools such as micrometers, calipers, verniers, bore gauges, height gauges, and thread gauges.
• Ability to perform First Article Inspections (FAI) to AS9102 standards.
• Experience with vertical milling operations in a CNC environment.
• Strong troubleshooting skills to adjust feeds, speeds, and offsets to maintain quality and efficiency.

Additional Skills & Qualifications

• Programming experience, including Mastercam or similar CAM software, is an asset.
• Experience with Haas CNC machines is an advantage.
• Exposure to Mazak machines and related controls is beneficial.
• Experience with both CNC mills and CNC lathes is an asset.
• Comfort working with CAM workflows and optimizing toolpaths.
• Strong attention to detail and commitment to quality in a precision machining environment.
