基于Web Services的并联机床制造服务系统

针对并联机床加工曲面零件的优势与目前并联机床未得到广泛应用之间的矛盾，开发了并联机床的制造服务系统。该系统将并联机床原有制造系统中的后置处理功能封装成Web services，包括编译、工作空间计算、干涉校验和运动学变换，应用面向服务的架构使并联机床的制造服务与异地制造企业协同工作，并给出了此架构下该系统的工作流程和功能模块。实例说明，应用Web services和面向服务架构的制造服务系统与传统的分布式系统相比，具有易集成性、松耦合性及易操作性，可以为企业减少成本、提高效率。

MANUFACTURING SERVICE SYSTEM BASED ON WEB SERVICES FOR PARALLEL KINEMATICS MACHINES

Parallel kinematics machine (PKM) is advantageous over the serial machine tools in processing thecomplex-surface products.A manufacturing service system for PKM is developed to provide the services of thecomplex-surface machining for potential geographically-dispersed manufacturing enterprises.In order to easily in-tegrate the external system,Web services are used to encapsulate post-processing functions of PKM legacy sys-tems,including compilation,workspace calculation,interfere calibration,and kinematics transformation.A ser-vice-oriented architecture (SOA) is proposed for the cooperative work between the PKM system and its client.The workflow and the function module of this manufacturing service system are presented.An example showsthat as a result of SOA and loose coupling,such a Web service-based manufacturing service system is easier to in-tegrate and interoperate with its client.Meanwhile,the system decreases the manufacturing cost and improvesthe efficiency than its former kind of distributed system.
