Keywords: Grinding process, chatter, ANFIS, kinematics 1. Introduction In cylindrical plunge grinding processes, the occurrence of chatter vibration is critical. This is because it compromises on the accuracy and surface finish of the ground part, (Hongqi and Shin 2007). Cylindrical
Jan 11, 2021 Find somebody who understands the difference between cylindrical plunge grinding and cylindrical traverse grinding and can do basic trigonometry. He or she will have to wisely take into account the wheel diameter and width, the workpiece diameter and height and the swivel angle — and whether you’ll have to do an extra traverse on the bottom.
Jun 26, 1992 Abstract: An optimization strategy is presented for intelligent control of cylindrical plunge grinding. The optimization strategy is designed to minimize cycle time while satisfying production constraints. Monotonicity analysis together with local linearization is used to simplify the non-linear optimization problem and determine the process variables for the optimal cycle.

Heidenfelder The speed ratio q is defined as quotient of cutting speed vc and workpiece peripheral speed v at the principle point D.
Jun 03, 2010 Cylindrical Grinding Problem Dear All, Yesterday i noticed a peculiar problem while OD grinding, On 1 side I would get spiral marks and on the return it would be fine finish. * The Table Feed in both direction is same [obviously]. * The Wheel is Clamped tight on the Flange, checked again and Dynamically Balanced.
Examples of limit charts derived for plunge feed centerless grinding are illustrated in Figures and rate is proportional to infeed rate, v f, in plunge centerless the particular conditions, the optimum workspeed is seen to be given approximately by v w = m/s, when grinding with medium carbon steel, AISI 1055, or with gray cast iron.

Dec 16, 2018 Problems Solve with a Cylindrical Grinder. In this kind of grinding cycle, it is vital to leave sufficient material along the workpiece’s diameter so that both the finishing and hardening operations can be done and surface quality is attained.
Dec 01, 2017 However, one of problems commonly reported when using the MQL technique is the wheel clogging phenomenon as a result of the inefficient chip removal from the cutting zone, then the chips lodge inside the pores of the grinding wheel, adversely affecting …
The reasons for the problems in internal grinding operations are the large contact arcs in the contact zone between the grinding wheel and the workpiece bore, a vibration behavior of the components involved in the active grinding process (high-frequency spindle, mandrel for the grinding wheel, workpiece and bore geometry) which is difficult to control.
