MAINTENANCE ASSISTANT (MACHINIST), GRADE 9
New York State Department of Civil Service
NATURE OF WORK
A Maintenance Assistant (Machinist) performs semiskilled machinist activities in the operation of machine tools in constructing and repairing metal parts of equipment and machinery.
Positions of Maintenance Assistant (Machinist) are located in only a few agencies.
CLASSIFICATION CRITERIA AND DISTINGUISHING CHARACTERISTICS
A Maintenance Assistant (Machinist) performs the more routine and repetitive tasks usually not requiring any planning or layout to achieve required dimensions. Incumbents follow specific instructions and work under the direction, observation and supervision of a Machinist. Maintenance Assistants (Machinist), in learning and perfecting their craft skills, may perform journey level activities under supervision or after receiving detailed instructions. Incumbents may supervise maintenance helpers, laborers and other relatively unskilled workers in performing manual tasks involving elementary skills.
There are a number of other specialized maintenance assistant classes having parenthetic designations describing the predominant trade areas to which the incumbent is assigned; i.e. carpenter, electrician, painter, and plumber and steamfitter. Although incumbents of such classes may perform tasks normally associated with more than one trade, most of their time is spent performing tasks typical of the trade indicated by the special title.
Incumbents of Maintenance Assistant positions without a parenthetic designating a trade specialty are usually found in relatively small maintenance staffs where such specialization is not desirable or in maintenance pools where specialization is not efficient. However, incumbents may be assigned to tasks such as those described for any of the specialized positions of Maintenance Assistant.
Maintenance Assistant is distinguished from Maintenance Helper by the latter's performance of relatively unskilled manual tasks in direct support of semi-skilled or skilled trades positions. Such tasks are performed under very specific instructions and the supervision of either a maintenance assistant or a journey level worker.
The position of Machinist is distinguished from Maintenance Assistant (Machinist) by the responsibility for setting up machine tools to specifications, planning a series of operations, and laying out stock for machining by applying knowledge of mechanics, shop mathematics, metal properties, and layout machining procedures. Machinists may develop specifications from general descriptions and draw and sketch products to be made. Positions of Machinist frequently supervise Maintenance Assistant (Machinist) positions in performing machinist work.
TYPICAL ACTIVITIES, TASKS AND ASSIGNMENTS
Maintenance Assistant (Machinist) operates such machine tools as lathes, shapers, milling machines, planers and radial drill presses following written or oral instructions in performing such machine operations as threading bolts, cutting keyways, grinding brake drums and valve tappets and planing cylinder heads. Illustrative tasks include the following:
· Installs proper cutting tools, sets machine controls determining sequence of operations, speed and depth of cut according to setup, and machining instructions and procedures.
· Machines metal parts to prescribed specifications and checks the accuracy of the work by the use of precision measuring devices such as micrometers and gauges.
· Manufactures on a repetitive basis metal items such as large bushings, special bolts and valve seat inserts not requiring difficult planning and layout.
· Cleans and lubricates machine tools.
· Cleans work area.
As assigned a Maintenance Assistant (Machinist) functions as a lead worker over a small maintenance crew usually consisting of maintenance helpers and laborers.
Under direction, incumbents participate in work in other maintenance specialties when not engaged in machining activities.
RELATIONSHIPS WITH OTHERS
The nature of Maintenance Assistant (Machinist) activities generally restricts relationships to oral communications with employees working within the same organizational unit. As assigned incumbents supervise a small maintenance crew characterized by frequent oral communications in assigning work and providing instructions. Written and oral communications with others are not typical of this class.
NATURE OF SUPERVISION
Maintenance Assistants (Machinist) are supervised by Machinists. Work priorities and the nature and extent of work to be performed are prescribed and materials and equipment are furnished. When necessary, the work to be performed is laid out by the supervisor who gives specific instructions, assists in performing the more difficult tasks and inspects the job while in progress and when completed to insure that instructions have been followed and that the quality of the work is satisfactory. However, a Maintenance Assistant (Machinist) may perform the activities of the class with considerable independence when supervision is not immediately available. In addition, incumbents are expected to perform the more routine and repetitive tasks with considerable independence.
As assigned a Maintenance Assistant (Machinist) supervises a maintenance crew consisting of maintenance helpers, laborers and other relatively unskilled workers by making assignments, giving instructions and providing assistance in performing the work.
MACHINES, TOOLS AND EQUIPMENT USED
A Maintenance Assistant (Machinist) uses the machine tools and equipment of the machinist trade including hand tools, precision measuring devices and a variety of machine tools.
· Working knowledge of machine shop methods, materials, tools and equipment.
· Basic knowledge of the mathematics of the machinist trade.
· Basic knowledge of the physical characteristics and uses of commonly used metals and alloys.
· Ability to use the tools, materials and equipment of the machinist trade.
· Ability to read and work from plans, drawings and specifications.
· Ability to understand and carry out written and oral instructions.
· Ability to stand for long periods of time and to do moderately heavy lifting.
· Ability to lead the activities of a subordinate staff.
Two years of experience in machinist work under the supervision of a skilled machinist, or completion of an appropriate two year technical school course in the machinist trade.
