Despite all these production practices,restrictions,
and controls,the original procedures involved in
machine design,analysis,and simulation remain
largely unchanged,as outlined by Younkin [2].These
processes,upon which the basic performance of
machinery systems depend,are lacking in rigour
compared to subsequent,mandatory,manufacturing
regulations that were imposed to improve machining
standards,consistency,and volume production targets.
Essentially,machine tool design generally employs
pointwise,lumped analysis methods.This approach
does not recognize spatial dispersion,irrespective
of the machine dimensions,mass,inertia,andstiffness properties.For analytical convenience,all
these characteristics are assumed to be located at
a single,undefined point in the space–time continuum,
as in reference [3].
Clearly,this assumption becomes increasingly
difficult to sustain with expanding machine dimensionality,
slenderness ratios,

Despite all these production practices,restrictions,
and controls,the original procedures involved in
machine design,analysis,and simulation remain
largely unchanged,as outlined by Younkin [2].
尽管这些生产实践,限制和控制,和机器设计、分析以及模仿有关的原始程序大部分没有改变,就如Younkin强调的那样.
These processes,upon which the basic performance of
machinery systems depend,are lacking in rigour
compared to subsequent,mandatory,manufacturing
regulations that were imposed to improve machining
standards,consistency,and volume production targets.
这些机器系统的基本操作依靠的程序,相比起后续的、强制的生产规程来说,却缺少严谨性,而这些生产规程是用于改进加工标准和加工一致性以及批量生产的
Essentially,machine tool design generally employs
pointwise,lumped analysis methods.
实际上,机床设计一般都采用逐点计算的,集中分析的方法.
This approach does not recognize spatial dispersion,irrespective
of the machine dimensions,mass,inertia,andstiffness properties.
这个方法不能辨认空间散布,并且和机器的尺寸,机器重量和惯性以及刚度这些特征没有关系
For analytical convenience,为了分析的方便
all these characteristics are assumed to be located at
a single,undefined point in the space–time continuum,
as in reference [3].所有的这些特性都会被假设成是位于空间中的一个独一的、未定义的点上-----如文献所说的,我们把它称为时间节.
Clearly,this assumption becomes increasingly
difficult to sustain with expanding machine dimensionality,
slenderness ratios,明显地,当机器的维度和长细比越来越大的时候,这个假设会变得越来越困难.
