Aerospace CNC Programmer – 3/4/5‑Axis Milling & Wire EDM

Hpfasteners; Houston (TX); On-site; USD 70,000 - 90,000; Full time

Job summary

Houston Precision Fasteners (HPF) seeks a skilled CNC Mill & Wired EDM Programmer to program, set up, and operate 3/4/5-axis milling and Wire EDM to produce aerospace tooling and fastener components.

The ideal candidate has deep ESPRIT CAM experience, tight tolerance machining, GD&T and proficiency with high-temperature alloys like Inconel 718, MP35N, A286, titanium. Join HPF's precision shop and contribute to critical defense programs.

Qualifications

• 3+ years of experience programming, setting up, and operating both CNC Mills and Wire EDM machines in a precision manufacturing environment (Aerospace, Defense, or Medical preferred).
• Proven offline CAM programming experience. ESPRIT CAM proficiency is strongly preferred (SolidWorks/Mastercam experience is a plus).
• Experience working with high‑temperature nickel alloys, cobalt alloys, stainless steels, and tool steels (Inconel, A286, MP35N, H13, D2).
• Expert knowledge of GD&T (ASME Y14.5) and engineering drawing interpretation.
• Deep understanding of G-code programming, macro variables, machine controls (Haas, Fanuc, Heidenhain, Mitsubishi, Charmilles, or ONA).
• Proven experience in part setup, fixture design, and precision alignment.
• High School Diploma or GED required; Machinist Apprenticeship, Trade School Certificate, or Associate Degree in Precision Machining/Manufacturing Technology highly preferred.

Responsibilities

• Develop, verify, and optimize G-code/M-code programs for multi‑axis CNC Mills and Wire EDM machines using offline CAM software (ESPRIT preferred).
• Select optimal cutting strategies, speeds, feeds, wire tension, burn settings, and tooling configurations for aerospace materials and hard tooling.
• Perform complete setups, workholding configuration, part prove‑outs, and production runs on CNC Mills and Wire EDM machines.
• Establish work offsets, zero points, wire threading parameters, and tool lengths accurately.
• Design and fabricate custom workholding, soft jaws, and EDM holding fixtures to support fastener manufacturing processes (hot forging dies, trim dies, thread rolling tooling, trim plates).
• Perform first‑piece and in‑process dimensional inspections using precision measuring equipment (micrometers, calipers, optical comparators, height gauges, pitch micrometers).
• Interpret complex engineering drawings, CAD models, and ASME Y14.5 GD&T callouts to ensure zero‑defect compliance under AS9100 quality management standards.
• Perform routine preventive maintenance on CNC mills and Wire EDM units (dielectric fluid management, wire guide inspection, filtration systems).
• Troubleshoot machining anomalies, tool wear, chatter, and program errors to improve cycle times and tool life.
