Investigation the Effects of Cutting Parameters on Geometric Accuracy of Machining Marine Propeller using 3D Photo-scanning Technique

Abstract

The measurement method and analysis experiences of 3D scanning instrument used in manufacturing industry is a novel for recent company before we are going to apply the 4.0 industrial era. The research purpose is to provide a measurement and analysis results of quality control and product improvement stage in the third industrial era. This paper presents an approach for accuracy measurement of complete scanning complex geometric of marine propeller blades. The geometric accuracy of marine propeller models, which has been finished by machining processes are measured using 3D photo-scanning technique. The effects of cutting parameters, that is step-overs and feed-rates, on the geometric accuracy are investigated. Inspection of geometric accuracy is performed by comparing the result of 3D scanning measurement of finished propeller with CAD design data. The results showed that greater step-over value, the deviation value tends to be smaller. Similar to the feed-rates, greater value of the feed-rates, the deviation value tends to be smaller
