Influence of the cutting fluid on process energy demand and surface roughness in grinding—a technological, environmental and economic examination

Abstract

The grinding process is characterized by a large number of undefined cutting edges that are simultaneously in contact with the workpiece to achieve a fine surface finish and a high geometrical accuracy. To enable an efficient grinding process, the application of cutting fluids is an indispensable factor. This investigation shows that-depending on the cutting fluid composition-the fluid has varying influence on the achieved technological results and on the energy consumption of the process. Therefore, it is important to identify a cutting fluid which balances technological, environmental and economic requirements. Against this background, this paper investigates the technological influence of different cutting fluids regarding the achieved surface roughness and consumed energy. On the basis of experimental data, regression models are derived and used to evaluate the environmental and economic impact. As significant extension of the state of research equation-based models for the relationship of cutting fluids and energy demand as well as quantitative indications of saving potentials are provided.

Deep Learning Approach of Energy Estimation Model of Remote Laser Welding

“…The purpose of this approach is to find optimal process parameters. For process optimization, Winter [9] measured energy use of a grinding machine and extended the concept to eco-efficiency [10]. In terms of laser processes, the laser device of an additive process has been investigated.…”

Development and testing of a novel glycerol/chitosan based biocide-free hydraulic fluid

“…The aim of the presented research work was to develop a novel, biocide-free, mainly glycerol, water, and CMC containing hydraulic fluid and thereby building on experiences gained with a glycerol-based cutting fluid (Winter et al, 2012;Wichmann et al, 2013;Stache et al, 2013;Winter et al, 2014). Particular attention was paid to a very good technical performance of the novel hydraulic fluid, its applicability in different sectors, its human and environmental compatibility, and the absence of biocides and mineral oil.…”
