“…The finite element method is being increasingly used as an effective route to predicting temperature distribution due to difficulties in measuring temperature of the cutting zone and tool rake face in experiments [12], [24][25][26][27]. The plastic deformation and friction at the tool-chip interface are the main source of heat during the cutting process.…”

The paper reports an advanced finite element analysis code for the investigation of the cutting process of rectangular groove. Three different restricted contact tools (RC tools) with rectangular, trapezoidal and double-trapezoidal shapes were employed in this study. The cutting force, feed force and rake face temperature distribution during the cutting process were analysed. The simulation results show that asymmetric tool-chip restricted contact shape causes the chip to break more easily than the symmetric tools. The RC tool shows significant reductions both in cutting force (6~8 %) and feed force (70~80 %) than traditional tools. It is also found that the RC tools give 12 % reduction in mean temperature on tool rake face compared to those of traditional tools. The simulation results indicate that the tools with asymmetric tool-chip contact shapes have advantages over symmetrical ones in terms of decreasing chip breakage, reducing cutting force and tool cooling.

“…Through the thermal analysis of the machining processes, the source of heat flux plays a key role. Most authors considered a uniform heat flux (Chang, 2007;Liu et al, 2009;Liu and Chou, 2007;Umbrello et al, 2007), while a select few considered a nonuniform heat flux in the rake face, e.g. (Haddag et al, 2013), to calculate the temperature distribution.…”

Grinding is one of the most complex manufacturing processes in industry and understanding its physics is still fairly limited due to the stochastic nature of the process. The physics behind the grinding process can be better understood through thermomechanical analysis of grain-material interactions, enabling the optimization of the process and grinding tool. When simulating the chip formation in machining processes, difficulties arise when the negative rake angle is large, when thermal effects on the tool and workpiece become prominent and when there is the necessity to consider damage within the constitutive equations of the workpiece material. These difficulties become further intensified given small depths of cut as in the case of grinding and the need for three-dimensional models. A coupled thermomechanical dynamic analysis is performed to simulate linear machining experiments effectuated by single diamond grains. Damage is described within a Johnson-Cook model. The damage parameters when machining Ti-6Al-4V are optimized in a three dimensional model and a new concept of applying a damage limit when machining with negative rake angle is suggested. Here, a Fortran subroutine is written to calculate the damage field variable. The simulated cutting forces and temperature in the tool as well as the workpiece are validated. Validation experiments are carried out by single grain machining experiments at a depth of cut of 30 m and at a linear cutting velocity of 0.8 m/s. Numerical challenges, such as chip separation criterion and settings of adaptive remeshing are addressed. Finally, it is shown that with an increase in the cutting edge radius, cutting forces and especially passive forces increase.
