Selected issues related to SEM-imaging and image analysis of spherical melted chips formed during the grinding process are presented and discussed. The general characteristics of this specific group of machining products are given. Chip formation phenomena, as well as their overall morphology, are presented using selected examples of near- and semispherical melted chips occurring singly or concentrated in clusters on the grinding wheel surface after the machining process. Observation of the spherical melted chips and acquisition of their images were carried out for grinding wheel active surfaces with microcrystalline sintered corundum abrasive grains SG™after the internal cylindrical grinding process of a 100Cr6 steel and Titanium Grade 2® alloy by use of a scanning electron microscope, JEOL JSM-5500LV. Analysis of the obtained SEM micrographs was carried out by Image-Pro® Plus 5.0 software to determine the selected geometrical parameters describing the morphological features of the assessed chips.

“…Chip morphology has been, for many years, the key factor characterizing machining processes. Many examples of investigations concerning chip morphology in order to obtain new knowledge about basic phenomena in machining processes such as turning [1,2], milling [3][4][5], drilling [6,7], and grinding [8,9] may be found in the literature.…”

“…The results showed that the increase in cutting speed results in the decrease in power consumption until a minimum value was reached, beyond which they increase. In hard turning, at low cutting speeds, high power is consumed due to the formation of BUE [17,18]. It has been illustrated that the power consumption is substantially affected by the variation of the feed rate and the depth of cut.…”

Off-line process control improves the efficiency of the manufacturing process through the manipulation of process variables. The present study uses a combination of Taguchi orthogonal array and analysis of variance to experimentally investigate the effect of cutting parameters on profile roughness parameters, tool flank wear and power consumption during hard and dry turning of AISI M2 steel with cubic boron nitrite cutting insert. The results reveal that the surface roughness and flank wear are significantly affected by speed and feed. The power consumption of the machine is substantially affected by the feed and the depth of cut. Thereafter, optimum values of performance characteristics are predicted.

“…The hard turning process is essentially a high speed, low feed and low depth of cut finishing process. The cutting speeds, as reported in various works, range between 100 and 250 m/min [14,[16][17][18][19][20]52]. In order to establish the correct combination of input parameters, trial experiments are to be performed which consume lots of time and manufac turing cost.…”

Hard turning is the process of machining hard ened steels that are above 45HRC. In manufacturing, hard turning has emerged as a potential area because of its many advantages over grinding as a finishing operation. In the present paper, a review is done on Design of Exper iment (DOE) techniques that have been employed on various hard turning processes by researchers. DOE is one of the widely used methods for experimental study of many manufacturing processes in engineering. It is a statistical approach in which a mathematical model is developed through a minimum of experimental runs. DOE predicts the possible output, based on the given input parameters in an experiment. The present study predomi nantly focuses on the usage of Response Surface Method, Taguchi's method and Factorial method in hard turning.
