Abstract

The abundant use of cutting fluids in surface grinding process and the corresponding costs and energy consumption have been a major sustainability concern. This paper identified the optimum depth of cut for surface grinding under controlled grinding parameters using compressed air cooling technique and dry cutting. The surface morphology and subsurface defects of the workpiece material (AISI 304 stainless steel) were measured and compared. It was observed that lower depth of cut had a better surface morphology than higher depth of cut. The effects of compressed air on tool life were equally evaluated. The heat dissipations on the grinding wheels were observed and analysed for both grinding conditions. In addition, the influence of compressed air on the surface integrity of the workpiece was also investigated. The results showed that lower depth of cut proved to have a better quality surface compared to higher depth of cut.

Highlights

Manufacturing involves a set of processes to produce a finished or a semi-finished product from raw materials [1]

Summary

Introduction

Manufacturing involves a set of processes to produce a finished or a semi-finished product from raw materials [1]. Machining is a common term used to summarise a list of processes that consist of the removal of material and modifications of the surfaces of a workpiece that has been produced using many stages of process beforehand [1]. One of the major types of material removal process is surface grinding. Grinding is used for precision and ultra-precision machining of workpiece as well as for high material removal rates [4]. The workpiece material is exposed to abrasive wear during the grinding process. Abrasive wear is the removal of material from a surface by a harder material moving along or impinging on the surface under load. Abrasive wear rate is inversely proportional to the hardness of the abraded workpiece and directly proportional to the applied load [5]
