CNC Machinist

2nd shift opening: 1:45pm - 11:15pm (Mon-Fri) XXXX RANGE: $30,00 - $35.00/hr (depending on experience) + $2 shift differential

We are looking for someone with CNC LATHE setup and operating experience. It will be huge plus if they know MAZAK machine control and experience with Y axis machining. Please place pre-screen questions and answers on resume at submittal.

Experience & Background

• How many years of experience do you have operating CNC and manual machines?
• Have you worked in an aerospace or other high precision, regulated manufacturing environment?
• What materials have you machined most frequently? (e.g., titanium, Inconel, aluminum, stainless steel, composites)
• Describe the most complex part you've machined. What made it challenging?

CNC Programming & Technical Skills

• Are you experienced with G-code programming, editing, or creating programs from scratch?
• Which CAM software have you used? (e.g., Mastercam, NX, Fusion 360, CATIA)
• What types of machines have you operated? (3 axis, 4 axis, 5 axis mills; lathes; Swiss)
• Can you explain how you verify and troubleshoot a new CNC program before running it?
• Have you ever optimized feeds, speeds, or tooling for difficult-to-machine aerospace materials? Give an example.

Quality, Tolerances & Inspection

• What tolerance ranges are you comfortable working with? (Aerospace often requires ±.0005? or tighter.)
• Are you familiar with GD&T (Geometric Dimensioning & Tolerancing)?
• What inspection tools do you regularly use?
• Calipers
• Micrometers
• Height gauges
• Bore gauges
• Surface plates
• CMM (if applicable)
• Describe your process for performing in process inspection on tight-tolerance components.

Aerospace Compliance & Documentation

• Have you worked with aerospace documentation requirements such as AS9100 or First Article Inspection (FAI/AS9102)?
• Are you comfortable completing shop travelers, quality logs, and nonconformance reports?

Safety, Equipment Care & Problem-Solving

• How do you handle machine tool wear or unexpected machine behavior during production runs?
• Describe a major machining issue you solved and how you approached it.
• Are you trained in machine safety, lockout/tagout, or hazardous material handling?

Work Style & Availability

• Are you open to overtime, weekends, or shift work if production requires it?
• Can you comfortably read and interpret aerospace-level blueprints?
• Do you prefer working independently or in a team-cell environment?

Position Summary

Operates various conventional and/or numerically controlled machining centers on semi‐complex jobs. Works from blueprints, sketches, planning sheets, verbal instructions, and/or engineering, tooling, or equipment information. Contributes to lean initiatives to increase productivity and reduce costs. Works with limited guidance in a team environment.

Responsibilities

• Sets up and runs multiple production machines.
• Performs machine operations (including reworking parts) such as cutting, shaping, deburring, forming, drilling, and reaming parts.
• Makes necessary machine adjustments and reports improper machine functioning or cutting action for correction.
• Aligns and fastens work using standard fixtures and established methods.
• Installs and adjusts cutting tools consistent with type and size of material being machined.
• Follows established manufacturing methods using standard production machines, materials, and tooling.
• Adjusts feeds, speeds, and depth of cut to machine quality parts, per documentation.
• Operates hand and power tools to deburr precision and complex machine parts in accordance with semi‐complicated engineering blueprints and route sheets to close tolerances.
• Inspects parts for conformance to specifications using measuring instruments such as gages, calipers, micrometers and comparators.
• Uses various types of magnification equipment (including a microscope) to detect and avoid damage to surfaces and critical areas.
• Visually inspects parts for burrs or damaged machined surfaces.
• Routinely maintains equipment to ensure cleanliness, accuracy, and reliability specific to division requirements.
• Accurately and regularly performs statistical process control (SPC) specific to division requirements.
• Actively implements lean initiatives by…
