Abstract

Belt grinding of flat surfaces of typical parts made of steel and alloys, such as grooves, shoulders, ends, and long workpieces, is a good alternative to milling. Several factors can influence the belt grinding process of flat surfaces of metals, such as cutting speed and pressure. In this work, the importance of pressure in the belt grinding was investigated in terms of technological and experimental aspects. The grinding experiments were performed on structural alloy steel 30KhGSN2/30KhGSNA, structural carbon steel AISI 1045, corrosion-resistant and heat-resistant stainless steel AISI 321, and heat-resistant nickel alloy KHN77TYuR. The performance of the grinding belt was investigated in terms of surface roughness, material removal rate (MRR), grinding belt wear, performance index. Estimated indicators of the belt grinding process were developed: cutting ability; reduced cutting ability for belt grinding of steels and heat-resistant alloy. It was found that with an increase in pressure p, the surface roughness of the processed surface Ra decreased while the tool wear and MRR increased. With a decrease in plasticity and difficulty of machinability, the roughness, material removal rate, reduced cutting capacity (Performance index) , material removal decreased, and the tool wear increased. The obtained research results can be used by technologists when creating belt grinding operations for steels and alloys to ensure the required performance is met.

Highlights

To satisfy the customer demands in terms of cost production and high-quality products, there is a huge need for developments in mechanical engineering, especially in the manufacturing sector [1,2]
The results showed that the effect of pressure on the output parameters of belt grinding of such materials has not been sufficiently reported in the open literature
The current study investigates and establishes dependences of efficiency indicators, such as surface roughness, material removal rate (MRR), grinding belt wear, and performance index, on the pressure during belt grinding of flat surfaces of steels and alloys

Summary

Introduction

To satisfy the customer demands in terms of cost production and high-quality products, there is a huge need for developments in mechanical engineering, especially in the manufacturing sector [1,2]. The product quality and abrasives used are highly important to achieve the desired production goals [3]. This is because belt grinding operations have a significant role at all stages of manufacturing [4,5]. The widespread use of belt grinding operations has determined its high demand [6]. Abrasive belts are often operated ineffectively due to the use of non-rational grinding modes [15]. The efficiency of flat grinding operation depends on many factors such as cutting mode [16], parameters of grinding operations (pressure) [17], workpiece material [18], etc. Zhe et al [20] studied the different contact pressures and their influence on the characteristics of belt rail grinding of
