Gun Barrel Rifling Broaching Process Real-time Monitoring System Design

It is artillery that rifle processes research to manufacture, the important craft link of the production line inside, to the artillery's technical and military tactics the index sign rose the function of the decision.The key equipments that rifle process is broaching machine.Tradition of all of broaching machines use explorator, in the operation dependable, automation degree and quantity control etc. aspect exsit irregularity, increasingly become the artillery to research to manufacture, the production line's bottleneck.It is solution that conduct and actions machine processes the equipments, numerical control resolve broaching machine to face the problem's a validity path, but general use numerical control system can't completely resolve all blemishs of the current broaching machine.This text bring upped a solution for aim atting broaching machine numerical control: general use numerical control system is responsible for motion control,process real-time monitor and control system that in exclusively research to manufacturing of broaching machine is responsible for dependable towards control consequently( machine position, load, appearance etc.) proceed examination, record, distinguish, storage etc., general use numerical control system and process real-time monitor and control system are in conjunction with work, each attends to own duties, guarantee reliability consistency of rifle process, and extended request for real-time data collection, storage, management, analysises etc.This text aims at the every kind of function request of broaching machine, and take to set up the process real-time monitor and control system 's software and hardware platform: Industrial control computer(IPC)+ digital signal processor(DSP), IPC system software is developed and operated under the Windows operate system the environment, have the interface of good person machine, simple to easily use;DSP system software is developed and debugged in the TI company CCS integration development environment, DSP chip guarantee the veracity and real-time of system control via high speed handle ability and abundant extended interface.The communications use CAN bus between IPC and DSP,solving the huge capacity data delivering, guaranteeing reliability. process real-time monitor and control system adopt the modularization method for designing, all parts of software and hardware are composed and designed according to modularization method, making the reliability and maintainability of whole system to consumedly increase.This text research is mainly several aspects: operation status data real-time collection of broaching process, information display,fault on-line examination and handle of broaching process, data information exchange and control among all parts of system and between monitor and control system and numerical control system, broaching craft parameters setting, processing procedure creating automatically, operation status data and system condition record information management. The result of research is already successfully applyed in the practical rifle broaching process ,and obtains good effect.
