Dim f As Double f为进给量,单位m
Dim π As Double
π = 3.1415926535
在代码起始部分需要对使用到得变量进行定义和赋予初始值。而且需要注意的是在对话窗口中,输入的各数值单位是毫米和角度,在代码中,标准的单位是米和弧度,所以需要编写计算式后,才能直接使用,而且VB程序中没有对圆周率π进行定义,未进行赋初值的常量系统均赋予其初值0,所以此处要对π定义并赋值。
a = Val(TextBox1.Text) / 1000
b = Val(TextBox2.Text) * π / 180
c = Val(TextBox3.Text) / 1000
d = Val(TextBox4.Text) / 1000 + c
e = 2 * π * Val(TextBox7.Text) / (Val(TextBox6.Text) * Val(TextBox8.Text))
f = -Val(TextBox5.Text) * Val(TextBox7.Text) / (1000 * Val(TextBox6.Text) * Val(TextBox8.Text)) 定义主要变量并赋值
