Tool feed rate influence

Chapter 7 elaborates various important influencing factors of EMM. Influence of lEG, temperature, concentration, electrolyte flow, and tool feed rate has also been described with the help of large number of practical results. Chapter 8 concentrates on various strategies to improve machining accuracy of EMM. Hybrid EMM teclmiques which are the newer developments to improve the effectiveness of EMM have also been included. Selections of optimal combination of EMM parameters validated by test results have also been incorporated to enhance the machining efficiency and accuracy. Chapter 9 includes numerous practical and industrial applications of EMM. Various factors which restrict the wider usability of this process have been discussed. This Chapter also focuses on how to minimize these adverse factors by applying various remedial measures. 

It is important to understand the influence of cutting conditions such as cutting speed, depth of cut, and feed rate on tool temperature. Kronenberg (Kronenberg 1966) proposed the following empirical equation by measuring the tool temperature using a tool-work thermocouple method ...

Several factors directly or indirectly influence the surface finish of machined parts, such as cutting conditions, tool geometry, work material, machine accuracy, chatter or vibration of the machine tool, cutting fluid, and chip formation. The objective of this research was to investigate the effects of major input parameters on the surface finish of parts produced by dry turning and to optimize the input parameters. From a user s point of view, cutting parameters—cutting speed, feed rate, and depth of cut—are the three major controllable variables as such they were selected as input parameters. 

The trepanning tool reduces the thrust force and torque during drilling of GFRP composites as compared with the twist drill. The torque behaviour was similarly influenced by the drill point geometries and the feed rate. A decrease in the feed rate reduces the thrust force, which can reduce the... 

The process is mainly influenced by the feed rate. To obtain optically smooth surfaces, feed rate must be reduced down to about 1 pm per revolution. The formation of compressive stresses in front of the tooling edge is desired in order to plasticise the material in this zone. The very low chipping depth is in the range of rounding of the diamond tool used for turning and, therefore, a run in time is preferred [288].
