8 Precision Engineering Terms

Below are some important precision engineering terms:

  • CNC

This stands for Computer Numerical Control. This is a computer which converts designs produced by a Computer Aided Design (CAD) software. The numbers produced can be known to be the coordinates of a graph. These control the movement of the cutter.

  • CNC Turning

This is a process where a cutting tool machine moves more or less linear with the rotating workpiece. The axes of the tool may be in a straight line and it may often have some curves or angles set. The term “turning” is saved for the external surfaces via the cutting action, the same cutting action is also used for internal surfaces. Internal surfaces include holes, which are of one kind or another. This process is called “boring”, the phrase “turning and boring” categorises a wider amount of processes. “facing” is where the cutting off faces happen with a turning or boring tool. This may be categorised under a few categories.

  • Planned Maintenance

This is a proactive approach to maintenance. On certain days, maintenance work would be scheduled to take place. This happens on a regular basis. The work being maintenance would be varied depending on the equipment or tools being used and the environment which the engineers would be operating in.

  • Environmental Performance

This is how the engineers perform environmentally compared to benchmarks which are all set against the National policy categories.

  • Annealing Marking

This is a type of laser marking where colour conversion is collected through a thermal action laser. The process relies on metals changing colour when they are heated, this is a familiar method as it is seen in the process of bluing steel.

  • Laser Marking

This is the defining of letters, markings or numbers using an intensive laser beam, this laser beam alters the material to create these. The method of laser marking and energy depends on the material you are trying to engrave. The laser markings are water resistant and effacement resistant which can lead to durability. The markings can be created quickly, automatically and individually.

  • Décolletage

This is the process of turning the microscopic range. This microscopic range is used to create small turned parts and is often involved in clock making or medical industries. Décolletage is done via a sliding lathe.

  • Sand Blasting

Sandblasting is where sand is forced through a nozzle and onto a surface which is being worked on using compressed air. This process helps to remove dirt and contamination and creates an abrasive effect which roughens the surface.
