Introduced the history, current condition and existing problem of the processing technology of NC simulation, compared NC simulation system theory and methods in existence domestic and international, combined the limit in technical level in person and experiment restrictions, the SuperMan-200L NC machine tool purchased by our college is studied in this paper.
Because heavy forgings are usually forged on free forginghydraulic press, possessing the machine is also a significant symbol indicating theproduction capacity, technical level of heavy equipments, the economy and nationaldefense strength of a country, having specific strategic significance.
The improving on the design mode and flow of die and the level of manufacture technology was partly stated in several ways, with improving the design and manufacture technology of the TOYOTA Die, being combined with the level of the auto die design and manufacture technology in our factory.
So by dimensional chain calculation we can improve the design level of the products plot, determine the tolerance of parts economically, assure the machine precision, and improve the quality of the products.
With the development and mature of the computer technology and numerical control, both of them are applied to manufacturing to implement the process automation.
Our estimates show that the present-day technical level with laser power of about 1 W provides sufficient sensitivity for detecting gravitational waves.
On a technical level, the authors describe the mirror's function in the painting of self-portraits and recommend it be used to draw foreshortened objects more easily and to judge the quality of finished paintings.
Most of FDI in China was from the developing countries and regions, which had a negative effect on the size and technical level of foreign capital enterprises.
The key to solving these problems is to enhance the scientific and technical level of monitoring, management, and restoration of water resources and associated water and soil components of local ecosystems.
The general layout of a steel plant is a complex standard to measure the level of its design and construction. According to present conditions arrangement of operations between the steelmaking shop and the rolling mills of the plant has great influence upon the general plan of the whole plant.The ingot teeming along the transverse axis of the steel shop (transverse teeming) is better than the ingot teeming along the axis parallel to the shop axis. This is more favourable for future change to continuous cast...
In the past the study on the collective control of the reeling thread troubles was carried out on the assumption that the technical standard of the reelers is the same. In this article it is assumed that the technical standard of the reelers in the collective control group is different from one another. Hence it brings forth a new theory for the collective control. By this theory the standard of the reelers of the collective control group was investigated. Through this investigation it is quite obvious that...
This script of scientific and educational film (it has been filmed) describes briefly the commonly adopted manipulating techniques of one side welding by shelded metal arc. It covers the key points for welding of different joint designs under different welding positions.It is hoped that this motion picture will play an important rule in facilitating welder training. The college students engaged in welding speciality could be also benefited from watching it.
