Oral Communication
  • Request services and supplies. For example, request parts from parts runners. Seek troubleshooting support from co-workers in various departments. (1)
  • Interact with clients when performing maintenance and repair work on equipment and machinery. For example, receive instructions about what components to change and seek approval to replace worn parts that were not on original work orders. (2)
  • Coordinate work and discuss assembly procedures with assembly team members and supervisors. For example, maintain ongoing communications with co-workers during the moving and installation of large sub-assemblies. Talk about alternative installation procedures with supervisors when parts are not fitting correctly. Share troubleshooting options when test readings and dimensions are out of range. Speak with other assemblers during shift changes to discuss work progress and concerns. (2)
  • Provide instructions, directions and explanations to helpers and apprentices. For example, give helpers instructions for assembling machinery and equipment. Provide apprentices with directions for setting up their workstations. (2)
  • Receive instructions and work assignments from co-workers, lead hands and supervisors. For example, receive reassignment instructions from lead hands when there are assembly stoppages. You are given instructions from co-workers when assembling unfamiliar equipment or when assisting them in troubleshooting equipment malfunctions. (2)
  • Share information about new technologies and assembly techniques and procedures with colleagues during trade shows and manufacturers' training sessions. (2)

Measurement and Calculation
  • Take measurements using rulers, tapes, meters and digital displays on instruments. For example, measure the dimensions of parts and the distance between them. Measure the quantity of oil to add to machines and use gauges to measure the hydraulic pressure in pumps when testing equipment. (1)
  • Calculate acceptable ranges for measurement parameters by adding and subtracting tolerances from ideal dimensions or values. For example, add and subtract half a volt to specified charging voltage to determine the operational voltage range for charging systems. (2)
  • Calculate the dimensions and placement of sub-assembly units and parts using measurements from scale drawings when additional dimensions are required to complete assembly. Verify that the dimensions conform to specifications by measuring depth, height, width and angles from manufacturing drawings using instruments such as rulers and protractors. (3)
  • Use specialized measuring tools and techniques to obtain precise measurements. For example, set up and use vernier callipers and depth verniers to obtain depth, width and distance measurements such as the distance between the inner ring of an air sleeve to the flange to a thousandth of an inch. Set-up, connect, and select appropriate scales on multimeters to measure the amperage and resistance of fuses, switches and relays in motors. (3)
  • Use trigonometry and geometry to determine height, depth and length. For example, use geometry to create equations to calculate the length to cut a sheet of metal. Use the thickness of the material, the number of bends and the angle of the bends as factors in the equations. Use trigonometry formulae to determine the travel distance required to achieve the correct arc angle in bends. (4)

Data Analysis
  • Compare readings for variables such as temperature, pressure, amperage and rotations per minute to specifications. For example, when setting up equipment, adjust it so that measurements match specifications or fall within acceptable tolerances. (1)
  • Calculate average test readings such as quantity of water per hour going through pumps. Compare these calculated values to specifications to ensure levels are within acceptable ranges and to draw conclusions about the functioning of equipment. (3)
Back to Top

Numerical Estimation
  • Estimate distances and angles to check placement and orientation of parts when exact measurements are not required. (1)
  • Estimate the weight of machinery and equipment to determine what lifting devices and procedures to use to move them. (1)
  • Estimate the time required for assembly jobs. Consider factors such as the number of components, parts and sub-assemblies to be put together, the complexity of assembly jobs and sequences and previous experience with particular equipment and machines. (2)

Job Task Planning and Organizing
  • Machine fitters receive their job tasks and priorities from their supervisors. They may determine the order of assembly within a general framework. Although the types of machinery they assemble change, their tasks are repetitive and do not need to be re-sequenced when interruptions occur. (2)
Back to Top

Decision Making
  • Decide to repair defective parts. Consider the cost of the repair, workload, ability to complete the repair and what work the next assembler is completing. Request approval from supervisors, depending on the complexity of the tasks and cost of the parts. (2)
  • Decide what tasks to assign to helpers. Consider the helpers' skills and experience, the complexity of tasks and your own ability to monitor the work. (2)
  • Decide when to place 'hold' and 'do not use' tags onto assembled equipment. For example, place hold and do not use tags onto parts and components when you consider them faulty. This ensures that supervisors and quality assurance examiners are aware of the faults. (2)
  • Decide the order in which to assemble parts and equipment when working on new product lines and modified equipment. Consider the individual tasks, what parts need to have operations performed by co-workers, what parts will interfere with the installation of others and what tasks can be streamlined to avoid repetition of activities. (3)
  • Decide to perform assembly and fabrication tasks not specific to your station or function. Most assembly requirements are listed but new and modified equipment may be missing assembly steps. You may need to reassemble equipment if you make the wrong decisions. For example, decide to paint specific parts or components before sending them to the next station. Consider whether the parts have been machined and the difficulty of painting them after assembly. (3)

Problem Solving
  • There are defects and missing and poorly assembled parts. Tag the pieces, request supervisors' feedback and repair faults. For example, parts such as hoses and belts are missing or defective. Speak with supervisors to locate the missing parts and to determine if you can substitute other parts before beginning the assembly of equipment. (1)
  • There are faulty designs and assembly procedures and inconsistencies between parts and drawings, which result in parts not fitting. Work with supervisors to locate alternative parts, different assembly procedures and design modifications, which will make them fit better. For example, a machine fitter is unable to use specified screws because weld modifications make a deeper weld depth. The fitter uses alternative screws or attachment methods approved by the engineering department. (2)
  • There are discrepancies between design specification and tool capacities. For example, discover that the torque required for bolts is beyond the maximum listed on Assembly Floor Sheets. Speak with co-workers from the engineering department who decide whether to allow variances to assembly and test procedures. (2)
Back to Top

Finding Information
  • Locate assembly information such as measurement and testing specifications, equipment readings, operational tolerances, material composition and troubleshooting procedures in technical data sheets and in troubleshooting checklists, flowcharts and decision trees. (2)
  • Draw on information from troubleshooting flowcharts, manuals, assembly drawings, co-workers, engineering staff and supervisors to find solutions for difficult equipment and part assemblies and malfunctions. (3)
Back to Top

Critical Thinking
  • Judge the quality and condition of products using knowledge of established quality control criteria. Use established evaluation criteria such as acceptable test readings, accurate fit between parts and the overall neatness and finish of assemblies. (2)
  • Evaluate the safety of workstations, tools and equipment operations. Consider criteria such as potential hazards, safety precautions and procedures used and the condition of equipment and tools. (2)
  • Evaluate the efficiency of assembly sequences and the set-up of workstations to complete specific tasks. Use occupational knowledge to identify criteria such as the type and repetition of motions and the frequency of tool usage. (2)
