MACHINIST 63021

07/01/92 G

 

CLASS CONCEPT/FUNCTION

This is a single class in the Machinist series that is responsible for setting up and operating a wide variety of precision equipment to fabricate, rebuild, and repair a machine and equipment repair parts and other components to precise dimensions. Positions have fabrication and machining responsibilities in either the agency's district equipment repair shop, or in the central office's Equipment division.

 

DISTINGUISHING FEATURES OF THE WORK

Complexity of Work: Performs work of moderate difficulty in calculating dimensions, setting up, adjusting, and operating a wide variety of precision equipment to perform various operations such as turning, shaping, boring, drilling, milling, and grinding to make finished parts and fittings from rough stock or by reworking parts within precision tolerances. Precision parts machined and/or fabricated may included threaded bolts and nuts, bushings, sprockets, splines, pulleys, flanges, collars, spindles, shafts, pins, ratchets, cogwheels, plow hitches, and other components, assemblies or tools that would be difficult to find for the fabrication, machining, and repair of parts for tractors, dump trucks, bridges, automobiles, ferryboats, drawbridges, and toll and tunnel facilities. Examples of equipment used in the machining process include lathes, milling machines, boring mills, drill presses, shapers, threaders, hydraulic presses, grinding and sharpening machines, welding equipment, and basic hand tools. Instruments and gauges used for precision measurements within close tolerances include metric and standard micrometers, calipers, dial indicators, flow meters, cylinder gauges, rules and tapes. Determines appropriate materials to be used in parts fabrication. Reads and interprets technical blueprints, sketches, drawings and diagrams. Work may require creating sketches or diagrams to determine fabrication and machining needs. Maintains records of materials ordered and used and of labor. Performs preventive maintenance and minor repair of equipment. May train or supervise others in the operation of equipment.

Supervision Given: Supervision is generally not a factor; however, some positions may train or supervise others in the use of applicable equipment.

Supervision Received: Receives general supervision from an Equipment Repair Supervisor, Equipment Repair Manager, or other labor and trades supervisory position.

Scope: Positions fabricate, rebuild, and repair parts, components, and tools for the Equipment Division or at a District Equipment Shop. Positions located in the Transportation Central Office Equipment Division Shop may also perform work for a district. Positions located at either a district or at the Equipment Division Shop may fabricate equipment repair parts or components for other state agencies.

Impact of Actions: Effective job performance results in effective equipment utilization through the fabrication and machining of parts to be used in equipment repair; and results in compliance with safety regulations and normal safety standards, which creates a safe work environment. Errors could result in serious injury, and could be costly in terms of equipment damage, materials, and equipment downtime and underutilization.

Personal Contacts: Frequent internal contact with district and residency staff to discuss machining and fabrication needs; other state agencies, such as State Police and the Department of Forestry, to discuss fabrication and machining needs. External contact with parts suppliers to locate, order, and purchase materials and parts.

 

KNOWLEDGE, SKILLS AND ABILITIES

Knowledge: Working knowledge of machine shop techniques and procedures; safety procedures of machines and tools used in area of assignment; of the properties of common metals and alloys; and some knowledge of equipment repair parts, their functions, and how they work, to effect electrical, mechanical, and hydraulic repair.

Skills: Skill in the setup and operation of a wide variety of machine shop equipment and measuring instruments of the trade, such as lathes, milling machines, boring mills, drills presses, shapers, grinders, threading machines, micrometers, calipers, dial indicators, sharpeners, flow meters, spray welders; and basic hand tools.

Abilities: Demonstrated ability to read and comprehend technical blueprints, sketches, diagrams, or drawings of components to be duplicated, or parts or tools to be fabricated, and/or to create sketches of parts or components to be fabricated and machined; to perform basic mathematical calculations including some geometry; to follow oral and written instructions, and to perform heavy manual labor.

 

QUALIFICATIONS GUIDE*

License or Certification: Certain positions may require a valid motor vehicle operator's license and/or a Commercial driver's license.

Education or Training: Graduation from high school or equivalent with training in machine shop practices.

Level and Type of Experience: Experience in machine shop setup and operation of a wide variety of related equipment and instruments for fabricating and machining parts and tools.

An equivalent combination of training and experience indicating possession of the preceding knowledge, skills and abilities may substitute for this education and experience.

 

CLASS HISTORY

This class was revised as a result of an agency study. This class replaces the Highway Equipment Machinist class, effective July 1992.
