German horse Er (Mahr) metric equipment company produces outline of two kinds of surfaces two dimension measuring instrument, one kind is the Perthmeter Concept of outline driving unit instrument, another kind is XC10 outline measuring instrument. Outline driving unit is the crucial part of the instrument, the basis needs but optional PCV, PGK, PRK and CD a medium kind. Their scanning length (the journey) each are different. It is with PCV200 exemple, it is hard usage, bulk the 2 dimension of light, high accuracy measure small, weight unit, water square amounts to 200mm to scanning length, high direction measures limits to amount to 50mm. Measure power adjustable between 2 ～ 120mN, need not the tool is OK very change conveniently scanning arm. Driver chooses those who measure arm of speed, scanning to rise to fall and locate by software control, full automatic give out measure an outcome. Measuring instrument of Mahr outline can measure the parameter of workpiece outline to have: Radius, angle, distance, coordinate is inserted and build regression axes of dot of circular arc of circle of linear, best-fitting, best-fitting, definition, crossing, linear coordinate, all be worth vertical line, all be worth a circle, all be worth circular arc to wait. Accordingly, to the outline of foregone design parameter, can will measure result and design parameter photograph to compare, get the deviation of outline is worth namely; To the outline of sealed design parameter, the measurement of classics instrument the ginseng of attainable outline is numeric.
