Design and manufacture CMM (Coordinates Measuring Machine) to measure geometric parameters of ship propellers

Abstract

Measuring and checking propeller geometry parameters is a mandatory requirement of classification organizations before installing propellers on ships. Currently, there are many methods and specialized equipment used to measure and check geometric parameters of ship propellers, each type has different functions and costs. This paper presents the results of research on the design and manufacture of CMM measuring equipment used to measure geometric parameters of fishing boat propellers including: pitch, blade profile, disc aspect ratio, propeller diameter. Apply this device to actually measure fishing boat propellers, as well as evaluate some factors about the durability and accuracy of the device.
