Machines may be programmed manually or with the aid of a computer. Manual prart programming; programming done by a computer is called computer aided programming (CAP). 机床可以手工编程或在计算机的帮助下编程。手工编程是 由人工完成的，而计算机辅助编程（CAP）是通过计算机完 成的. Sometimes a manual program is entered into the machine’s controller via its own keypad. This is known as manual data input (MDI). This text will focus on manual part programming. 还有大家熟知的手动数据输入方式（MDI），它是通过其 自带键盘，将程序输入到机床的控制器。本课将重点讲述手 工编程。

machines? Smith: A good question, boy. You know, uh-hm…., NC, or
numerical control, actually refers to the control of a machine tool or any other processing machines by using a series of mathematical information, or numerical data. It means the work of machines is controlled by a numerical control program.
Mary: But what do you mean by overall operation?

Dialogue
Smith: Uh-huh, by it we mean the general industrial production practice. For example, NC should be adopted whenever there is similar raw material and work parts are produced in various sizes and complex shapes. Those production shops that may have frequent changeovers will surely benefit from NC progr (to Prof. Smith) Excuse me, sir, I’m Tom, one of your students in this class. Could I ask you some questions?

5 FEED FUNCTIONS
F0, 25, 50, 100% F0: allows a fixed feedrate to be set for each axis by parameter No.1421. For detailed information, refer to the appropriate manual of the machine tool builder.
·Feed functions (ⅰ) Rapid traverse. When the positioning command (G00) is specified, the
tool moves at a rapid traverse feedrate set in the CNC. (ⅱ) Cutting feed. The tool moves at a programmed cutting feedrate.
5 FEED FUNCTIONS
5.3 CUTTING FEED
Feedrate of linear interpolation (G01), circular interpolation (G02, G03), etc. are commanded with numbers after the F code.
5 FEED FUNCTIONS

5 FEED FUNCTIONS
CAUTION When the speed of the spindle is low, feedrate
fluctuation may occur. The slower the spindle rotates, the more frequently feedrate fluctuation occurs.
