Job Description
This role combines full-cycle CNC programming and hands-on machining to produce high-quality parts in a dynamic machining center environment. You will program primarily in Mastercam using G and M code, set up and operate CNC mills or lathes, and take ownership of parts from blueprint through final machining. The position is ideal for someone with strong G&M code proficiency who enjoys both programming and running complex jobs in a job-shop or high-level setup environment.
Responsibilities
- Read and interpret blueprints, dimensional data, surface locations, and GD&T to understand part requirements.
- Determine the sequence of machining operations and select appropriate tooling and inserts for each job.
- Create, validate, and modify CNC programs using Mastercam, including transitioning SolidWorks models into Mastercam for CNC interface.
- Review and verify programs using G and M code before starting setup and machining operations.
- Set up CNC mills or lathes by installing and adjusting jaws, vises, stops, and other workholding devices.
- Set up tooling, including tool selection, tool length and diameter offsets, and proper tool holding for each operation.
- Operate CNC milling or turning equipment to perform surfacing, reaming, boring, drilling, tapping, and other required machining processes.
- Edit existing programs on the machine as needed to improve quality, efficiency, or to address issues encountered during machining.
- Change out and sharpen tools as required to maintain part quality and meet dimensional tolerances.
- Use precision measuring instruments such as micrometers and calipers to inspect parts and verify conformance to specifications.
- Handle all aspects of the machining process, including programming, setup, machining, and producing finished parts.
- Work with a range of part quantities, typically from single-piece runs to batches of up to 50 parts.
- Perform multiple setups per day, typically between 1 and 5 setups depending on part size, complexity, and quantity.
- Safely operate a 15-ton overhead crane to obtain, move, and position raw stock and large components.
- Maintain a clean and organized work area and contribute to a safe, efficient, and collaborative shop environment.
- At least 5 years of experience setting up and programming CNC lathe machinery, or equivalent high-level CNC setup experience depending on department.
- Strong proficiency in G and M code, including the ability to read, write, and troubleshoot programs.
- Hands-on experience programming CNC equipment, with a focus on creating and editing programs for milling or turning operations.
- Ability to set up and operate CNC lathes and CNC mills, including workholding, tooling, and machine offsets.
- Proficiency using Mastercam for CNC programming, including validating toolpaths and post-processed code.
- Ability to read and interpret engineering blueprints, dimensional drawings, and GD&T callouts.
- Experience setting up tooling, editing programs at the machine, and changing out or sharpening tools as needed.
- Competence using precision measuring tools such as micrometers and calipers to verify dimensions and tolerances.
- Capability to work independently through the full machining process from program creation to finished part.
- Ability to safely use an overhead crane to move and position stock and large parts.
- Ownership of basic personal tools appropriate for CNC setup and machining work.
- Previous experience in a job shop environment, handling a variety of parts and frequent changeovers.
- Experience with 6-axis mill/lathe combination machines.
- Background in toolroom or manual machining, supporting a strong understanding of machining fundamentals.
- Experience in high-level setup roles where frequent setups and complex parts are common.
