Profession milling machine operator

Milling machine operators set up, program and control milling machines, designed to cut excess material from metal workpieces using a computer-controlled rotary-cutting, milling cutter. They read milling machine blueprints and tooling instructions, perform regular machine maintenance, and make adjustments to the milling controls, such as the depth of cuts or the rotation speed.

Knowledge

• Quality and cycle time optimisation

  The most optimal rotation or cycle time and over-all quality of a tool or a machine's processes.

• CAM software

  Different tools for computer-aided manufacturing (CAM) to control machinery and machine tools in the creation, modification, analysis, or optimisation as part of the manufacturing processes of workpieces.

• Quality standards

  The national and international requirements, specifications and guidelines to ensure that products, services and processes are of good quality and fit for purpose.

• Manufacturing processes

  The steps required through which a material is transformed into a product, its development and full-scale manufacturing.

• Statistical process control

  Method of quality control that uses statistics to monitor processes.

• Types of metal

  Qualities, specifications, applications and reactions to different fabricating processes of various types of metal, such as steel, aluminium, brass, copper and others.

Skills

• Consult technical resources

  Read and interpret such technical resources such as digital or paper drawings and adjustment data in order to properly set up a machine or working tool, or to assemble mechanical equipment.

• Monitor automated machines

  Continuously check up on the automated machine's set-up and execution or make regular control rounds. If necessary, record and interpret data on the operating conditions of installations and equipment in order to identify abnormalities.

• Read standard blueprints

  Read and comprehend standard blueprints, machine, and process drawings.

• Interpret geometric dimensions and tolerances

  Understand and assess the models and symbolic language of the GD&T system indicating engineering tolerances.

• Remove inadequate workpieces

  Evaluate which deficient processed workpieces do not meet the set-up standard and should be removed and sort the waste according to regulations.

• Remove processed workpiece

  Remove individual workpieces after processing, from the manufacturing machine or the machine tool. In case of a conveyor belt this involves quick, continuous movement.

• Set up the controller of a machine

  Set up and give commands to a machine by dispatching the appropriate data and input into the (computer) controller corresponding with the desired processed product.

• Troubleshoot

  Identify operating problems, decide what to do about it and report accordingly.

• Perform machine maintenance

  Perform regular maintenance, possibly including corrections and alterations, on a machine or machine tool to ensure it remains in a proper productive state.

• Operate precision measuring equipment

  Measure the size of a processed part when checking and marking it to check if it is up to standard by use of two and three dimensional precision measuring equipment such as a caliper, a micrometer, and a measuring gauge.

• Dispose of cutting waste material

  Dispose of possibly hazardous waste material created in the cutting process, such as swarf, scrap and slugs, sort according to regulations, and clean up workplace.

• Perform test run

  Perform tests putting a system, machine, tool or other equipment through a series of actions under actual operating conditions in order to assess its reliability and suitability to realise its tasks, and adjust settings accordingly.

• Use automatic programming

  Utilise specialised software tools to generate computer code from specifications, such as diagrams, structured informations or other means of describing functionality.

• Ensure equipment availability

  Ensure that the necessary equipment is provided, ready and available for use before start of procedures.

• Supply machine

  Ensure the machine is fed the necessary and adequate materials and control the placement or automatic feed and retrieval of work pieces in the machines or machine tools on the production line.

• Use CAM software

  Use computer-aided manufacturing (CAM) programmes to control machinery and machine tools in the creation, modification, analysis, or optimisation as part of the manufacturing processes of workpieces.
