Graduation from High School or GED, plus graduation from a technical school, an apprenticeship program, or completion of a formal four-year training program that meets the satisfaction of the Shop Supervisor and the Operations Officer, is a plus. In addition, has three years’ experience in CNC and or Manual Milling and Lathes producing parts at close tolerances.
Machinist Skills and Qualifications:
Attention to Detail, knowledge and the ability to use a variety of machines: CNC Mills and Lathes and or Manual Mills & Lathes, Drill Presses, Grinders, Saws and other tools and equipment. Knowledge skills and abilities of Machine Codes for CNC machines; ability to make code adjustments at the Machine setting is a plus, Thorough understanding of equipment and tools needed to achieve different finishes as required. Has full range of using precision measuring and gauging tools, inspecting work being performed. Knowledge of and skills to utilize all equipment in shop. Math including algebra, geometry, trig, or calculus and related formulae. Converts easily and quickly between inch and metric. Converts reading on drawings between fractions and decimals. Knowledge of the different characteristics of materials, their structural and property effects. Materials include Aluminums, Stainless Steels, Titanium, Brass and other alloys; Polycarbonates, Ultem, Acrylic, Peek, etc. Experience working with Composites a plus.
Training in programming software used by the shop for CNC machines; e.g Feature Cam, or Fusion 360
