“…Superabrasive wheels offer many advantages over conventional grinding wheels such as longer wheel life, higher material removal rates, and better surface finish. However, dressing superabrasive wheels encounters fast dresser wear, especially when a single-point diamond dresser is used [1,2]. To improve the efficiency of dressing superabrasive wheels, laser-assisted dressing (LAD) has been proposed by utilizing a laser beam to soften locally the bonding materials in the wheel and consequently to facilitate the dressing process.…”

Laser-assisted dressing (LAD) has been proposed to prepare efficiently superabrasive grinding wheels by significantly reducing dressing forces and dresser wear. In this paper, a transient, three-dimensional heat transfer model is presented for LAD of superabrasive grinding wheels, where the effective thermophysical properties of the porous heterogeneous wheel are calculated and applied to the thermal model. Temperature measurements are conducted with an infrared camera and the excellent agreement between the measured and predicted temperatures show the validation of the present model for LAD of grinding wheels or, generally, laser-assisted machining of composite materials. To evaluate the influence of LAD on superabrasive wheels, grinding tests were carried out using a CBN wheel prepared by conventional and laser-assisted dressing respectively. The grinding tests show that LAD under proper conditions could improve the performance of CBN wheels.

“…Therefore, the time dependent characteristic of Inconel 718 in the grinding process must be taken into consideration as a product of the microscopic modes for proactive process design [6,7]. The grinding performance of cBN wheels varies significantly as the wheel wears down which imposes great challenges in cost-effectively utilizing the wheel and process control [8].…”

The time dependent behavior of grinding is expressed as the change of process output measures as a function of time during grinding. Although the wheel capability will be restored by dressing, the time dependent behavior of grinding during one dressing skip is determinant on the grinding quality variation in terms of surface integrity and workpiece geometric accuracy. Therefore, understanding of grinding time dependent behavior in relation with the wheel-workpiece microscopic interaction is critical for wheel and process development to achieve stable grinding processes. In this paper, the high speed grinding of inconel 718 with cBN grinding wheels is carried out. The time dependent behavior is recorded to represent the characteristic features. And the microscopic wheel topography is measured under SEM throughout the whole grinding process so as to reveal the root cause for the time dependent behavior and its impact on the workpiece quality variation.

In this paper, a data acquisition system was constructed for examining grinding performance of a plunge grinding machine. The system is capable of simultaneously recording power assumption of main spindle, grinding normal force, and material removal of a workpiece. Through grinding experiments for cylindrical workpieces, parameters of grinding process including normal force, power consumption, and time history of diametric error were obtained. With the obtained parameters, the stiffness and time constant of the grinding system were being derived such that the performance of the grinding machine was well evaluated. The configured system described in this paper can be applied to improve grinding performance through further online compensation process.
