skill/competence

cross-sector

Measure flatness of a surface is an essential skill of the following occupations:

Stone planer: Stone planers operate and maintain planing machines that are used for stone blocks and slabs finishing. They manipulate the stone and ensure that the required parameters are according to specifications.
Metal planer operator: Metal planer operators set up and operate a planer, which is a metalworking machine designed to cut excess material from a metal workpiece using linear relative motion between the planer’s cutting tool and the workpiece in order to create a linear toolpath and cut.
Straightening machine operator: Straightening machine operators set up and tend straightening machines designed to form metal workpieces into their desired shape using pressing practices. They adjust the angle and the height of the straightening rolls and select the settings for the pressing force required to straighten the workpiece, taking into account the end product’s yield strenght and size, without excess work hardening.

Measure flatness of a surface is optional for these occupations. This means knowing this skill may be an asset for career advancement if you are in one of these occupations.

Tumbling machine operator: Tumbling machine operators set up and operate tumbling machines, often wet or drie tumbling barrels, designed to remove excess material and burrs of heavy metal workpieces and precious metals and to improve surface appearance, by rotating the metal pieces in a barrel together with grit and potentially water, allowing for the friction between the pieces mutually and with the grit to cause a rounding, smooth effect.
Surface grinding machine operator: Surface grinding machine operators set up and tend surface grinding machines designed to apply abrasive processes in order to remove small amounts of excess material and smoothen metal workpieces by an abrasive grinding wheel, or wash grinder, rotating on a horizontal or vertical axis.
Cylindrical grinder operator: Cylindrical grinding operators set up and tend cylindrical grinding machines designed to apply abrasive processes in order to remove small amounts of excess material and smoothen metal workpieces by multiple abrasive grinding wheels with diamond teeth as a cutting device for very precise and light cuts, as the workpiece is fed past it and formed into a cylinder.
Filing machine operator: Filing machine operators set up and tend filing machines such as band files, reciprocating files and bench filing machines in order to smoothen metal, wood or plastic surfaces by precisely cutting and removing small amounts of excess material.
Deburring machine operator: Deburring machine operators set up and tend mechanical deburring machines designed to strip metal workpieces of their rough edges, or burrs, by hammering over their surfaces in order to smoothen them or to roll over their edges in case of uneven slits or sheers in order to flatten them into the surface.
Stone polisher: Stone polishers operate grinding and polishing tools and equipment in order to smooth stones.
Metal polisher: Metal polishers use metal working equipment and machinery to polish and buff almost finished metal workpieces in order to enhance their smoothness and appearance and to remove oxidisation, tarnishing the metal after the other fabrication processes. They may operate equipment using diamond solutions, silicon-made polishing pads, or working wheels with a leather polishing strop, and tend to these materials ensuring their effectiveness.
Jewellery polisher: Jewellery polishers ensure that finished jewellery pieces are cleaned by customer demand or prepared for sale. They may also perform minor repairs. They use either hand tools such as files and emery paper buff sticks and/or hand held polishing machines. They also use mechanised polishing machines such as barrel polishers.
