On this basis a virtual model of the grinding machine was built. This model simulates exactly the kinematic of the ma-chine and is able to calculate the position of the tool in rela-tion to the workpiece at any time of the grinding process. At this point, it is possible to add a frequency to the tool and the

The concept of KSIM is based on the observed micro- and macroscopic cause and effect chain in grinding and simulates the grinding process as a penetration between the enveloping profile of the grinding wheel and the workpiece . Therefore, the micro and macro geometry of the grinding wheel and workpiece have to be modeled.

Belt grinding has become an important production process, in some cases replacing conventional grinding operations such as the grinding of camshafts. Belt speeds are usually in the range of 2,500 to 6,000 ft/min. Machines for abrasive-belt operations require proper belt support and rigid construction to minimize vibration.

the grinding process was simulated. Zhang et al. (2019) used the discrete element method to simulate the grinding process of corn straw. The shape classification of broken corn straw was studied and verified by experiments. The results showed that the discrete element method was feasible for simulating the grinding process of corn straw.

During the remanufacturing process the machinist is mostly concerned with grinding the rod and main journals. Upon initial inspection of the crankshaft, with the use of the micrometer, the machinist will determine what bearings need grinding. Indicators that a journal needs grinding include if the surface has wear and make it rough to the touch.

This positioning of the dresser wheel axis at a 90-degree angle is the XING dressing technique. "For diamond wheel dressing, the dressing wheel still wears as much as or more than the grinding wheel, but now the dressing wheel is always a perfect radius," Mr. Drechsler says. "So that eliminates one of the huge variables in that process.".
