Software And Hardware Designs For The General Detecting Instrument Of Axisymmetric Body

The total production of axisymmetric workpiece has accounted for a large percentage of manufacturing industry. Along with wide application of internal-combustion engine, axisymmetric workpiece such as cylinder liner, plunger has played more and more important role in national economy. With the rapid development of modern industry, the traditional axisymmetric workpiece detector can no longer fulfills the requirement of on-line detection, axisymmetric workpiece detector of high precision and high efficiency has become the trend of development.This paper presents a general detecting instrument of axisymmetric body using a coordinate measuring system based on the combination of the contact measurement and non-contact measurement. It can fulfill the requirements of industrial production as high precision and on-line detection, and it also has advantages like good generality and openness. Besides these, it is an intelligent instrument to some extent.The main research works are as follows.According to the characteristics of the axisymmetric body, the traditional and standard CMM is reformed to make this instrument be more suitable for the detection of the axisymmetric body, and to lower manufacturing cost. This instrument inherits advantages of the contact measurement and non-contact measurement, so it has both high precision and high efficiency. It also has good openness and expansibility, because its motion control system is based on a dual CPU architecture composed by PMAC and IPC, and also because its measurement software has good openness. This paper presents a complete motion control system with various hardware modules and makes reasonable parameters for it. This system uses PMAC to complete functions such as handwheel, protection of the touch trigger probe and operation panel. Intelligent measurement software is edited for this instrument, and the designing thought, realizing method of the whole software and the detailed implementation steps for one-key fast measurement are included in this paper. According to relevant country or industry safety standards, the preliminary hazard analysis is made, and some safety measures are taken to ensure the safety and reliability of the operation. The basic principle of MSA is introduced, and bias, stability, linearity, repeatability, reproducibility and other important statistical characteristics are researched as its main contents. Finally this paper makes a actual evaluation for this instrument according to the assessment methodologies and procedure of MSA.
