Proficiency exam
Learner Outcomes: 

Students will be able to: demonstrate safe work habits and operating procedures; clean and maintain personal work area and equipment; select and appropriately use cutting fluids; appropriately use Personal Protective Equipment (PPE) and identify environmental and safety considerations established by the EPA, OSHA, and listed in SDS publications; identify, select, and calibrate precision and semi-precision measuring tools; measure workpiece to verify compliance with print specifications; display knowledge of quality control standards and process improvement, including SPC; identify the properties and characteristics of common metals and their effect on machinability; describe the AISI/SAE and UNS steel identification systems and heat treating processes and objectives; interpret blueprints including geometric dimensioning and tolerancing (GD and T) symbols; develop an order of operations (process plan) based on blueprint specifications; identify and appropriately use hand tools and power hand tools; grind and shape tools using a pedestal/bench grinder; perform semi-precision and precision layout; identify parts and preventive maintenance of a band saw; explain safe principles of operation; set up and perform band saw machine operations; identify parts and preventive maintenance of a lathe; explain safe principles of operation; select and maintain appropriate tools; calculate appropriate cutting speed, feed rate, and depth of cut; grind and form lathe tools; explain various workholding methods (e.g., independent and universal chucks, collets, faceplate, between centers, steady and follower rests); set up and perform lathe machine operations (e.g., turning, boring, threading, taper turning, knurling, grooving and cut-off, drilling and tapping, filing, polishing); identify appropriate uses for carbide inserts and parts and preventive maintenance of a mill; explain safe principles of operation; select and maintain appropriate tools; calculate appropriate cutting speed, feed rate, and depth of cut; explain various workholding methods (e.g., mill vise, table set-ups, angle plates, indexing heads, v-blocks); set up milling machines (e.g., head alignment, vise alignment, tool holder selection, establishing a part zero, set DRO use); perform milling operations (e.g., pocketing, slotting, hole-making, peripheral and face milling); identify parts and preventive maintenance of a surface grinder; select appropriate grinding wheel; explain safe principles of operation (e.g., wheel mounting and dressing, ring testing, workholding, grinding parallel and perpendicular surfaces); describe axis and coordinate systems; read and write basic G and M codes; perform basic setup and operation for CNC lathe (e.g., work offset, tool offset, workholding devices, toolholding devices); perform basic setup and operation for CNC mill (e.g., work offset, tool offset, workholding devices, toolholding devices); identify parts and preventive maintenance of a drill press; determine appropriate tooling and workholding devices; and explain safe principles of operation (e.g., drilling, reaming, countersinking, counterboring, tapping). Performance Component:  Milling Operations (55%); Lathe Operations (45%).

Instruction: 

NOCTI and NBS exams assess individuals' end-of-program knowledge and skills in an online proctored proficiency examination format. In addition, some programs administer a NOCTI/NBS performance component test to assess application of skills.

Credit recommendation: 

In the lower division baccalaureate/associate degree category, 1 semester hour in Introduction to Engineering Technology, Introduction to Manufacturing Engineering Technology, or Introduction to Precision Manufacturing Technology (5/12) (12/16 revalidation). NOTE: An additional 1-2 credits may be awarded based on successful completion of the Performance Component when given in conjunction with the written proficiency examination.
