GEARS PROFILE SCANNING WITH A 3D COORDINATE MEASURING MACHINES

Abstract

Measurement is an integral part of our everyday lives. It is something that most people take for granted.

In more recent times, the emphasis on Statistical Process Control (SPC) for quality improvement has accelerated the demand for faster and more accurate measurements. Coordinate Measuring Machines (CMMs) have become more capable to fulfill these growing requirements.

As computer-aided design (CAD) has become more popular, reverse engineering has become a viable method to create a 3D virtual model of an existing physical part for use in 3D CAD, CAM, CAE or other software. The reverse-engineering process involves measuring an object and then reconstructing it as a 3D model.

The purpose of this paper is to examinate a process of reverse engineering (trough scanning the surface of two gears), scan points on a surface, make a solid 3d part from the point cloud, and after that for validating the process, there will be made a measurement of the gears based on the model.
