processes, such as grinding (Shaw 1996). In these processes the chips are formed more like an extrusion process near the radius of the cutting edge, because the rake angle is highly negative. Milling, for example, has its own particularities, such as variation on the undeformed chip thickness h), interrupted cuts,(
The elastic state at contact wheel–workpiece interface is a critical issue during robotic belt grinding process that significantly influences the finishing profile accuracy. Establishing a reasonable undeformed chip-thickness (UCT) model that suits to this operation is considered a feasible approach to clarify the cutting mechanisms. In the present paper, an elastic .
Higher cutting ratio denotes that the cutting action is good. l 1 = length before cutting l 2 = length of chip after cutting b 1 = width of chip before cutting b 2 = width of chip after cutting α = rake angle of tool β = shear angle The volume before cutting is equal to the volume after cutting. i.e., the volume of metal cut off from workpiece equal to the volume of the chip.

Jan 01, 2012· The most common equation for maximum chip thickness in grinding, h m, is some variant of: where C is the cutting-point density, r is the shape factor, v w is the workpiece velocity, v s is the wheel velocity, a e is the DOC and d e is the equivalent diameter.
Typically, creepfeed grinding results in a lower undeformed chip thickness relative to surface grinding, thereby improving surface finish on the workpiece and reducing wheel wear. However, this advantage comes with a few drawbacks. Creepfeed grinding applications tend to draw more power and have higher forces.
