Development of Fault Diagnosis Models Based on Predicting Energy Consumption of a Machine Tool Spindle

CNC vertical lathe is the main on products. The domestic and foreign demand is also very big. The key part of the high precision is on the control of the spindle. This design is with the German SIEMENS company programmable controller (PLC), S7-200 as the main controller; Germany SIEMENS company 6 ra7075 dc speed regulator, Z4 dc speed regulating device of dc motor, dc speed control was adopted to realize efficient and accurate control of machine tool spindle, and the electrical principle diagram is given.

Remote Fault Diagnosis

Based on the authors previous work of developing an expert system for fault diagnosis of CNC machine tool, this paper studied the theory and method of CNC remote fault diagnosis expert system based on B/S, and presents schema and structure of the expert system in detailed. Case based reasoning is used for the multi-alarm diagnosis, and rule based reasoning is used for single-alarm diagnosis. At last fault diagnosis expert system was designed and developed making use of C# and ASP.NET.

Cylindricity Error

Abstract The design of machine tool spindle for minimum cylindricity error is presented. The shape of the spindle portion between the bearings, usually cylindrical, is reconfigured to increase the spindle rigidity. Two methods of reconfiguration are presented. In the first method, the spindle is reshaped as a smooth body of revolution. In the second method, the spindle is reshaped as a stepped shaft. Effects of bearings rigidity and fatigue stresses are also considered.
