On the commensuration of plastic plowing at the microscale

Study on ploughing phenomena in tool flank face – workpiece interface including tool wear effect during ball-end milling

“…The instantaneous equivalent position angle of the cutting edge fragment, which can be found in equation (3), is determined based on expression (4):…”

“…In order to calculate a value of the average (equivalent) uncut chip thickness per 1 tooth h ze_av , it is necessary to take into the consideration the value of the average working angle of the tool φ av in equations (3,4). A value of φ av angle is dependent on the conditions of mapping the tool in the workpiece material, related to the surface inclination angle (Fig.…”

“…An important factor influencing the surface finish constituted during precise or micro ballend milling processes is the ploughing phenomenon [2]. According to Tsybenko et al [3], ploughing is a component of abrasion phenomenon, which in turn is the one of fundamental wear modes of ductile materials. Thus, the operational properties and strength of a machined surfaces can be influentially affected by the ploughing of a workpiece during the chip decohesion process.…”

A review of advances in tribology in 2020–2021

“…The relative activity of slip systems changed depending on the grain orientation, and dissociated dislocations occurred during wear while indentation is dominated by full dislocations. They compared the austenitic steel results with those of cupper and cementite steel, and observed that the conservation of contact area, elastic recovery, and the front pile-up development were the dominant mechanisms [323]. To simulate the grinding process of single crystal silicon carbide (SiC) with diamond grit, single scratch experiments with a simulative grinding test rig were performed [324].…”

Recovery of Scratch Grooves in Ti-6Al-4V Alloy Caused by Reversible Phase Transformations

“…While the effect of the microstructure of Ti-6Al-4V alloy on its mechanical properties, including hardness and Young's modulus, has been extensively studied, there is a lack of information about the effect of the Ti-6Al-4V microstructure on its elastic recovery, which should be pronounced at high H/E ratios. At the same time, recent studies have indicated that elastic recovery substantially affects the ploughing of metals, which is the main mechanism of abrasive wear [11,12].…”
