On-siteQuality Assurance$34.17–$42.71/hrFull-time
Responsibilities
- Review assigned Jira tickets to determine material, tooling, fixturing requirements with autonomy.
- Ability to sort through tasks using the Critical Path Method to complete assigned machining requests in the most optimal order to meet deadlines and increase machine uptime.
- Discuss with engineering teams the issues related to manufacturability or timing, provide Design for Manufacturing (DFM) feedback, modify in CAD submitted parts as discussed to ensure successful completion of task.
- Ability to quickly summarize part requirements, apply roughing toolpaths and get machine running in as little time as possible (often
- Program parts using high end CAM software (Fusion 360, Powermill, Camplete)
- Operate the GUI Control and Setup of high end multi-axis machining centers.
- Understand speeds/feeds, depth of cuts and all other tool cutting parameters for a wide variety of materials, and the ability to apply these quickly to process jobs with a minimum of delay.
- Participate in team/peer discussions with suggestions on how to process the more complicated jobs, including fixturing and tooling requirements.
- Quick setup of mission critical parts which could disrupt company production schedules, and prevent excessive costs incurred by outside vendors.
- Review large quantity jobs to optimize program toolpaths, speeds, and feeds to reduce overall processing time.
- Perform inspection tasks to ensure part conforms to required critical dimensions and specifications utilizing advanced GD&T and engineering drawing reading abilities, using standard measurement equipment (verniers, calipers, micrometers, bore gauges, gauge pins, height gauges).
- Utilize 3D Scanning Equipment and corresponding software (Polyworks) for full virtual inspection of machined parts.
- Maintenance including monitor filters, oil and grease levels, machine calibration and adjustment.
Qualifications
- 4–6 years of experience in a CNC machining environment, working with Fusion 360, Mastercam, Powermill, or similar software.
- Proficient in working with 3D CAD data to create or modify existing 3D models.
- Program, setup, and operate 3- to 5-axis CNC Mills and Lathes, with a strong preference for Fanuc, Heidenhain, or Haas controls.
- Proficient in blueprint reading and Geometric Dimensioning & Tolerancing (GD&T), with the ability to review G-code to troubleshoot or verify toolpaths before running.
- Strong understanding of various machining processes, tooling, and materials (e.g., aluminum, steel, plastics).
- Excellent attention to detail and a commitment to producing high-quality, precise parts within +-0.002" tolerance or tighter.
- Inspect your own parts using standard precision measuring instruments (micrometers, calipers, gauges) to ensure compliance with tight tolerance specifications.
- Associate's Degree or Certificate in Machining Technology, CNC Programming, or a related field is highly desired.
- Adherence to safety protocols and a clean, organized work environment.
