Centerless grinding works best at machining the outside diameter of simple, cylindrical parts. It involves feeding a workpiece between a stationary grinding wheel rotating at high speeds and a slower regulating wheel which spins and drives the part, in the case of through-feeding. An angled workblade secured between the grinding and …

This paper proposes a control-oriented model for the cylindrical grinding process in the state-space format. Existing models of the grinding process contain, either explicitly or implicitly, several dynamic relationships among various process variables, based on which a nonlinear state-space model can be derived. After a series of …

In CNC cylindrical creep-feed grinding, the depth of cut (DOC) can be as much as 0.300" or more in one pass, depending on material hardness and form depth. Peripheral feed rates are typically 1" to 10" per minute. A second pass is usually performed for the desired surface finish, and size tolerance to 0.0002".

First, grinding is a widely known process. Independent of their shape, most workpieces can be ground. Hard turning, on the other hand, has geometric limitations, which is the case for long and thin components. While hard turning is an option for finishing parts, it's not the preferred one. Precision grinding processes can achieve a 6 Ra ...

In cylindrical grinding operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at much higher r.p.m. than the work. The work centres are mounted on a table which can traverse at various feeds so that the entire length of the work passes to and fro in front of the wheel.
