ABSTRACTThe general purpose of the occupational analysis is

to provide workable, basic information dealing with the many andvaried duties performed in the machine trades occupation. Thedocument 'ens with a brief introduction followed by a jobdescription. The bulk of the document is presented in table form.Fifteen duties are broken down into a number of tasks and for eachtask a two-page table is presented, showing on the first page: tools,equipment, materials, objects a.:ted upon; performance knowledge(related also to decisions, cues and errors); safety--hazard; and onthe second page: science; math--number systems; and communications(performance modes, examples, and skills and concepts). The dutiesinclude: maintaining machinery; performing bench operations,precision and semi-precision measurements, and heat treatingoperations; operating pedestal grinder; and setting up and operatingcut off saws, drill presses, lathes, shapers and slotters, verticaland horizontal milling machines, surface grinder, universal grinder,tool and cutter grinder, arbor press, and electrical dischargemachine.

FOREWORD

The occupational analysis project was conducted by The Instructional MaterialsLaboratory, Trade and Industrial Education, The Ohio State University in con-junction with the State Department of Education, Division of Vocational Educa-tion pursuant to a grant from the U.S. Office of Education.

The Occupational Analysis project was proposed and conducted to train voca-tional educators in the.techniques of making a comprehensive occupationalanalysis. Instructors were selected from Agriculture, Business, Distributive,Hone Economics and. Trade and Industrial Education to gain experience indeveloping analysis documents for sixty-one different occupations. Represen-tatives from Business, Industry, Medicine, and Education were involved withthe vocational instructors in conducting the analysis process.

The project was conducted in three phases. Phase one involved the planningand development of the project strategies. The analysis process was basedon sound principles of learning and behavior. Phase two was the identifica-

tion, selection and orientation of all participants. The training and work-

shop sessions constituted the third phase. Two-week workshops were heldduring which teams of vocational instructors conducted an analysis of theoccupations in which they had employment experience. The instructors were

assisted by both occupational consultants and subject matter specialists.

The project resulted in producing one hundred two trained vocational instruc-tors capable of conducting and assisting in a comprehensive analysis ofvarious occupations. Occupational analysis data were generated for sixty-one

occupations. The analysis included a statement of the various tasks performed

in each occupation. For each task the following items were identified:tools and equipment; procedural knowledge; safety knowledge; concepts andskills of mathematics, science and communication needed for successful per-formance in the occupation. The analysts data provided a basis for generatinginstructional materials, course outlines, student performance objectives,

criterion measures as well as identifying specific supporting skills and

knowledge in the academic subject areas.

Preface

In the last few years outstanding advances have been made in the machine trades area. The

technical knowledge and new machining processes have been a boom to the modern day machineshop. With all the advances made some basic skills exist that existed many years ago. In

this occupational analysis the participants have analyzed many of the basic tasks importantfor a beginning machinist to perform.

This occupational analysis was drawn up to provide a list of the duties, tasks, science,math, and technical knowledge of the tools and equipment used in the machinists trade.

ACKNOWLEDGMENT

We wish to acknowledge the valuable assistance rendered by the followingsubject matter specialists. They provided input to the vocational instruc-tors in identifying related skills and concepts of each respective subjectmatter area and served as training assistants in the analysie process duringthe two-week workshops.

Job Description

A machinist works with metals and metal removal to form parts of a predetermined sizeand shape as indicated by a blueprint or shop sketch. This is accomplished through theproper setup and use of precision measuring tools, lathes, drills, milling machines,grinders, metal cutting saws, shapers, heat treating equipment, hand tools and otherspecialized machinery found in today's machine shops.

In all duties and operations, accuracy, proper tools usage, and safety are practiced.Blueprint reading, sequence of operation, and applied math are necessary skills to asuccessful machinist.
