Profile-graph controled by micro-computer

Measuring curved surface of plow

Abstract

It is tried to make the profile meter which measures the curved surface of a plow in three dimensions, saves its data on a floppy disk and reproduces them on a plane board in two dimensions. This is able to measure the curved surface in the maximum size of 1250mm×1250mm×1000mm. The curved surface is measured at the each small displacement of Δx on x-z plane changing y position.
This profile meter consists of a micro-computer and an electro-mechanical part. As the meter is supported with microcomputer and its programs, it is possible to measure the curved surface automatically and is easy to operate the meter, The error of measurement by this equipment is 0.29% against actual measured length 700mm. For more accuracy, the mechanical part of this equipment will be improved.
