Abstract


The cam is one of the key parts of the automated machinery , due to the complex shape, high processing requirements , it is difficult to process in the field of machinery manufacturing parts . In reference to a large number of domestic and foreign scholars research work on the basis of design adaptive controller , a microcontroller - based grinding force has a certain practical significance . The main contents are as follows : Analysis of the Problems in the cam grinding , on the basis of in -depth study of the cam grinding process , the re- measurement and calculation of all the required parameters for system modeling , the cam mathematical process model . Grinding force control requirements , designed the two grinding force to adapt to the controller , PID controller and fuzzy controller . For the former controller , PID regulator relationship between the parameters and system time domain performance indicators , critical ratio method parameter tuning ; fuzzy controller , fuzzy control rule table , the preparation of a single-chip fuzzy control statement to determine the quantization factor and the output of the input scale factor . Design a MSP430 MCU as the core of the grinding force adaptive controller hardware , the software part . On the hardware part of the main signal acquisition , LCD display, power , speed , serial communications section gives specific circuit , made ??a brief introduction of the chip ; adaptive controller in the software part of the SCM process , through a program designed to control the hardware module controller able to complete the operation in an orderly manner , in order to complete the communication between the microcontroller and the CNC system , the original numerical control system has been improved . Describes the simulation of the microcontroller program debugging method , validated by the system debugging MCU grinding force to adapt to the feasibility of the controller ; fuzzy controller simulation using MATLAB Simulink simulation software tools , grinding force changes to verify the effectiveness of the design curve .
