ABSTRACT A corrugated paper arrangement for manufacturing printed corrugated paper cuts, in which a corrugated paper machine has an integrated rotary printing machine with several printing stations, and at least one longitudinal cutter and...
摘要：模具设计是一个知识密集型的过程。本文介绍了一个基于知识化、参数化、模块化和基于特征的集成计算机辅助设计、计算机辅助工程模具设计系统。为注塑成型和模具的设计开...
AbstractAn automatic brush plating system was developed to eliminate the disadvantages resulting from the operator in conventional brush plating.With this system, Ni/nano-Al2O3 composite coatings on 45 steel substrates were prepared from an...
# Springer-Verlag London Limited 2008Abstract In progressive dies, two or more stations are usedto produce sheet metal components. In each station, one ormore processes are applied. The progressive dies reduce thetime and cost of producing c...
Figure 2.41 shows the results for the medium pier. It can be seen that there is a goodagreement in terms of both the amplitude and the frequency content of the response.The agreement is representative of the correlation for the other two pie...
In many of the problem thus far , the student has been asked to disregard or neglect friction . Actually , friction is present to some degree whenever two parts are in contact and move on each other. The term friction refers to the resistan...
Stamping Die - Stamping in the cold, the material (metal or non-metallic) processing into parts (or half) of a special technical equipment, called cold stamping die (commonly known as Die). Press - is at room temperature, using the die inst...
A general algorithm for profiling and dressing grinding wheels when using a grinding spindle on a CNC lathe Remarkable progress is being made in the technology for grinding complicated geometrical parts. Today, some factories are considerin...
Abstract: This thesis focuses on a general lathe spindle，quantitatively analyzes the machining precision with spindle swinging in geometry way and derives a mathematical expression of machining errors at different swing frequencies． By...
Abstract This paper discusses issues regarding in-situ methods of obtaining sound power at a point in a heating, ventilating and air-conditioning (HVAC) duct system. Such a method is being used as part of a larger investigation on acoustica...
