Temperature-based method for determination of feed increments in crankshaft grinding

Detailed Thermo-Kinematic Analysis of Face Grinding Operations with Straight Wheels

“…Finally, the energy partition (ε) was calculated, implementing the theory and partition functions developed in [11] where local and global scale thermal effects are considered. The developed model is also capable of simulating the temperature distribution in the workpiece diameter and corner radius, as in [4]. As predicted, there is a local maximum temperature in the radius, but the full simulation shows that maximum temperature with axial approximation is always reached in the outermost diameter of the face.…”

“…On the other hand, as in [4], the aim here is to develop an expression for estimating the specific energy based on Equation (9). Experimental adjustment of this expression will serve as an input for estimating the total power and heat generated in future processes.…”

“…Metals 2020, 10, 524; doi:10.3390/met10040524 www.mdpi.com/journal/metals Face grinding with straight wheels enables grinding of opposite workpiece faces using a single fixture, thereby increasing the flexibility of the process. However, the use of this technique could lead to grinding burn and uneven wear on the wheel profile, as demonstrated in [3,4], where crankpin grinding with straight CBN wheels was thoroughly investigated. A classification and description of the different feed variants or strategies (radial or angle plunge, single-step axial and multi-step axial feed) is presented in [5], which summarizes the basic kinematics and flexibility offered by each strategy.…”

“…In [4], Drazumerik focused on optimizing the process through a combination of axial and radial feeds by establishing a maximum temperature limit for each of the three studied grinding zones (the diameter, the radius, and the face). For this purpose, a temperature simulation model was developed based on the estimation of an aggressiveness-driven specific energy.…”

“…Moreover, the ability to altogether remove lubricant was an essential step towards a truly sustainable supply chain. Drazumeric et al [ 17 ] suggest analyzing the surface temperature distribution along the grinded profile to select the correct feed increments for improving production rates while avoiding thermal damage. Using this method, grinding with the absence of burns was achieved, avoiding the long consuming trial-and-error approach.…”
