On the Mechanics of the Grinding Process Under Plunge
Two broad categories of grinding action are recognized; one where negligible ploughing and rubbing take place and where the plunge velocity versus normal force intensity curve is a straight line through the origin, the other where ploughing and rubbing predominate and the plunge velocity versus normal force intensity curve is concave upward.

This paper presents the effect of grinding wheel contact stiffness on the plunge grinding cycle. First, it proposes a novel model of the generalized plunge grinding system. The model is applicable to all plunge grinding operations including cylindrical, centerless, shoe-centerless, internal, and shoe-internal grinding. The analysis of the model explicitly describes transient behaviors during ...

For the first time, the cylindrical plunge grinding by structured wheels was simulated in this study by the mathematical modeling of the process kinematics. The simulation includes the whole steps of plunging, i.e. during both radial infeed and spark-out time. It was shown how the twist is transferred to the workpiece by a structured wheel. The ...

2021-8-20 Use oscillation (a common practice in plunge ID grinding). Many grinding machines today have variable speed controllers, so changing the wheel’s speed can be carried out by simply editing the CNC program or adjusting the spindle speed controller. Other machines might require manually changing pulleys and belts.

Surface grinding technique: roughing corner/finishing corner
2021-11-2 Surface grinding technique: roughing corner/finishing corner. A few years ago, when I got my first surface grinder, Buck suggested a technique that I now use a lot. Case in point: I cut a 50 x 400mm strip of 1.2842 (90MnCrV8 or AISI O2 tool steel) from a 10 x 150 x 400mm plate. The plate was ground parallel both sides (Blanchard) but after I ...
