department in time. The application of above method in a quality improvement process is represented
Abstract: Based on the analyzing the fact of slewing bearing production, the primary need for
software of the corporation is determined. On this condition, it has discussed the main designs,
which include the framework of software, key categories, and design of method and so on. Some
examples are given. Through using this software, we can not only reduce the workload of design of
nonstandard slewing bearing which is repeating and heavy, but also avoid misplay of the designer.
This software also provides the precondition for Computer-Aided Process Planning (CAPP).
Through the using of the software, we can increase the rate of eligible product, reduce the cost of
production and fulfill time limit for client better.
Abstract: Since Zhengzhou was affirmed for state key city of MIE and demonstration city of Henan
MIE in 2002, ERP and ERP’s element technologies have been demonstrated the application, and the
demonstration system having the dint of arouse and radiates has been built, which its layout was
reasonable and the structural layer was clear. In demonstration enterprises, the development period
of new products was shortened from 153 days to 102 days. Contribution rate of MIE in the new
product was raised from 37.4% to 51.3%. The occupancy of stock funds was decreased from 40%
to 27%. On this foundation, aiming at the midium and small enterprises, four sharing MIE platform
were set up. At the same time, the element technologies of informatization personalization were
applied. So, the coordinate development mode of medium and small enterprises MIE was put
forward. The preliminary result showed that this strategy could solve the bottleneck problem of
medium and small enterprises MIE and it could become the basis of the enterprise cluster MIE
Abstract: This paper adopted the photoelectric micro measurement system based on CCD which was
independently developed by Laboratory of Process Automatic and Detection Harbin Institute of
Technology to detect dimension of the small precise parts. Under the various focusing status, it was
discovered that articulation of focusing has huge effect on the measurement of measurand. According
to the characteristics of measurand, we adopted the entropy function as the evaluation function of
automatic focusing, developed a special software to process entropy value of the picked images, and
obtained the relationship of focusing evaluation function and measurement error through a large
number of experiments. The experimental result effectively verified the effect of articulation of
focusing on dimension measurement.
Abstract: Motorized spindle is high speed machining unit combined with hidden motor and
machine tools axis, which has advantages of high speed, stepless transmission, zero transmission
chain, and is applied in machine center widely. Key technologies are combined together in
motorized spindle designing, such as high speed motor, bearing, manufacturing and assemblage. It
is strict in assembling to guarantee rotating precision and dynamic balance and is different from
common machine tools designing due to characters of high speed and hidden motor. Hydrostatic
bearings have advantages of high carrying capacity, lower friction, and better holding precision, the
heat problem is extrusive, but the future of hydrostatic motorized spindle is considerable. Modal
and thermal performance analyses are necessary for motorized spindle designing. With modal
analysis, inherent frequencies are confirmed, which could be of help to avoid sympathetic vibration
in machining. It provides evidence for designing cooling system of thermal performance analysis.
Abstract: Laser direct manufacturing and re-fabricating have been used in many important fields in
recent years. However, simulation and measurement of velocity fields in carrying gas and powder
particles are still a challenge. In this paper finite difference method has been selected to simulate the
velocity fields of powder/gas fluid. A novel DPIV system has been developed to measure the
velocity fields. The DPIV system mainly consists of Nd+:YAG laser and CCD camera. Comparing
the result of DPIV measuring with computer simulating, a good agreement can be obtained. After
further developing, DPIV will become a useful device for laser manufacturing.
Abstract: Curvature fiber optic sensors are a kind of novel low cost sensors that can detect
curvature directly and distinguish the positive bending and negative bending. This kind of sensor is
used to detect torsion deformation of shaft in this paper. The optimal direction of curvature fiber
optic sensor was analyzed in osculating plane and rectification plane and maximal sensitivity was
gained. The results show that sensor response to the torsion angle is linear approximately. Torsion
angle, curvature and bending direction of shaft were measured simultaneously by using curvature
fiber optic sensors.
Abstract: A modular design idea oriented to client customization is proposed to achieve product
diversification and personalization. The Key technology of customized design is studied to meet the
market's requirement of short cycle, high quality and low cost in product design and manufacturing.
In the detailed design stage, the method of Top Basic Skeleton (TBS) is applied, which improves
the rapid response ability of product design and shortens the product development cycle. On this
base, a rapid design method of customized vacuum casting machine is illuminated. In the dynamic
and changing market environment, the rapid design method plays an important role in improving
the competitive power of enterprise.
Abstract: Intensive processing for meat requires security, reliability, and efficiency, dreadfully
demanding the automation of the process. A newly mold system was optimum-designed with three
revolving positions for automated sticking in the material feeding, compression, and productknockout.
The ratio of compression was taken with values in the range of 15-25% for the perfect
shape and stringing rate. Surfaces of the mold were designed with mathematical planning of SUMT
penalty function, and referent parameter values were obtained. Final decision was chosen from the
nine designs, reaching the requirements that the contours of the mold on the section was so
designed that it gained a closed figure approaching a circle, with the ratio of long and short axels
being about unit. The curves were simple and few, and faired. Virtual and physical experiments
have shown that the mold design is of feasibility, and with the current study the difficult problems
have been solved of productivity, stringing rate, and automation of the meat strings, setting up the
technical basis for the transformation of the production patterns from the conventional
labor-concentration to the modern technique-concentration in intensive meat processing industry.
