3.1.3 Other Independent Process Parameters

These three process variables - reduction, cone angle, and friction - are independent in that the
process planner may exercise a degree of freedom in choosing their values. The severity of
friction, for instance, is controlled, within limits, by choices of lubricant, die material and finish,
speed, etc.

The above three parameters, namely, reduction, cone angle and friction are the primary factors
affecting the process. Their effects on the first dependent parameter, the drawing or extrusion
force, will be analyzed first. Other independent parameters also play a role during processing.
For example, the drawing or extrusion force is linearly proportional to the flow strength of the
material, but when inertia forces are neglected, it is independent of the speed. The power, on the
other hand, is linearly proportional to speed. Furthermore, we will first consider isothermal
processing, where temperature is not a factor and then extend the treatment to handle adiabatic
processing and temperature effects. Thus, at first, only the effect of the three independent
parameters (r%, a, and friction) is considered.

3.1.4 The Dependent Variable

The force required for drawing or extrusion can now be characterized. In Fig. the drawing
force F (or drawing stress Fxf = F front/Af) is obviously a function of reduction (larger reduction
requires higher force), of cone angle, and of friction, and similarly for the extrusion force F (or
extrusion stress Fxb = F back/Ao). In short, the motivation force or stress causing the drawing or
extrusion is a dependent variable which is a function of reduction, cone angle, and friction.
Description of the drawing force, for example, as a function of these three independent variables
may be undertaken by either an experimental approach or an analytical approach. Each approach
can be aided by the other. Both approaches will be reported here and the results will be
compared.

3.1.3 其它独立工艺参数
三种工艺变量————减速度,模角和摩擦力————是相互独立的,因为工艺策划人员在选择它们的值时有一定的自由度。例如,摩擦力的大小可以通过选择润滑油、模具材料和表面处理、以及速度等将其控制在某个范围内。
上述三个参数,即减速度、模角和摩擦力是影响工艺的主要因素。我们先来分析它们对第一依赖参数,拉拔力或挤压力的影响。其它独立参数也对工艺起作用。
