Highspeed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels. On the other hand, very low grinding wheel speeds, in the order of 3,000 to 4,000 fpm (about 15 to 20 m/sec) are needed for the surface grinding of various types of .

Machining vibrations, also called chatter, correspond to the relative movement between the workpiece and the cutting vibrations result in waves on the machined surface. This affects typical machining processes, such as turning, milling and drilling, and atypical machining processes, such as grinding.. A chatter mark is an irregular surface flaw left by a wheel that is out of true in ...

· The effects of temperature on autogenous grinding can be immediately divided into rheological effects and mechanical effects. The rheological effects are a result of the substantial increase in the viscosity of water as the freezing point is approached. The change in apparent slurry viscosity which results from changing temperature is shown in Figure 1. As can be seen, the effect at .

Grinding burn is caused by excessive heat dissipation into the part material. As materials cool as rapidly as they heat, the material undergoes a treatment similar to a tempering process. At high enough tensile stresses, caused by the grinding burn at the outer edges of the material rim zone, the material could undergo micro cracking. Dynamic strain causes the micro cracks to grow into greater ...

· Mechanical effects and proper grinding result in a compressive residual stress at the surface. This is beneficial for fatigue. Thermal effect produces the opposite effect, with a residual tensile field at the surface. As the part is locally heated, the surface layer expands, but it is constrained by the lower undisturbed material. Compressive residual stress occurs at the surface. As the part ...

· The grinding process can be described in terms of time t in a time domain model. At any time, wheel ADOC δ w (t) must be equal to infeed u(t) of the grinding wheel, minus contact deformation y c (t), machine deflection y m (t), and wheel wear δ s (t), as shown in the following equation, (10) δ w (t)+δ s (t)=u(t)−y c (t)−y m (t). Two regenerative feedback loops should be taken into ...
