Grinding System

To monitor the precision cylindrical grinding process, an estimation of the time constant of grinding system, using acoustic emission signal, is presented during infeed period in this paper. Acoustic emission signals generated during precision grinding are sensitivity and present challenges for accurate and reliable process monitoring. Experiments demonstrate the results of the acoustic emission sensing approach in estimating the time constant. This estimation of the time constant can be used to analyze the properties of mechanical materials of the workpiece with the same grinding conditions.

Grinding System

A high-precision grinding method is presented to the marine controllable pitch propeller. Developed the four-axis simultaneous grinding system based on the abrasive belt grinding principle, and studied the key technologies of the grinder, such as the heavy-duty belt grinding head, the controllable pitch propeller grinding CNC programming software, etc. And on these bases, we have done the four-axis simultaneous heavy belt grinding test verification on the surface of the controllable pitch propeller blade with the grinder, providing a reference to determine the reasonable marine propeller belt grinding process parameters.

The Mathematical Model

Controlling the tooth errors induced by the variation of diameter of grinding wheel is the key problem in the process of ZC1 worm grinding. In this paper, the influence of tooth errors by d1, m and z1 as the grinding wheel diameter changes are analyzed based on the mathematical model of the grinding process. A new mathematical model and truing principle for the grinding wheel of ZC1 worm is presented. The shape grinding wheel truing of ZC1 worm is carried out according to the model. The validity and feasibility of the mathematical model is proved by case studies. The mathematical model presented in this paper provides a new method for reducing the tooth errors of ZC1 worm and it can meet the high-performance and high-precision requirements of ZC1 worm grinding.
