According to the actual operating conditions of NC gear C form grinding machine, the physical model of the nonlinear vibration of grinding wheel is established finally by analyzing the key parts of the grinding machine in the process of .A harmonic disturbance is acting on the machine, so use the following expression for displacement amplitude (X) of grinding wheel (1) Here, Y is the amplitude of vibration of floor, k is stiffness of isolator, c is damping constant of isolator, m is the combined mass of grinding machine and wheel, and is frequency of vibrations. Write the expression for harmonic disturbance acting on the machine.
May 26, 2015 Grinding Factor for grinding wheel selection 1.Constant factor d. Type of grinding machine Light machine is subjected to vibration. For harder grinding wheel the poor condition machine would be ok For soft grinding wheel the heavy rigidly constructed and well maintained machine.The machine industry has undergone several developments in the past years, and reducing the cost and time required for machine designing is important. In this study, the vibration characteristics of a precision grinding machine were obtained through experimental modal analysis and finite element analysis. The experimental modal analysis employed single point excitation, and the equipment used.
