COMPUTER NUMERICAL CONTROL PROGRAMMING BASICS FOR CNC MILLING

Abstract

Almost all current CNC controls use a word address format for programming. (The only exceptions to this are certain conversational controls). By word address format, we meant that the CNC program is made up of sentence-like commands. Each command is made up of CNC words. Each CNC word has a letter address and a numerical value. The letter address (X, Y, Z etc) tells the control the kind of word and the numerical value tell the control the value of the word. Used like words and sentences in the English language, words in a CNC command tell the CNC machine what it is we wish to do at present time.
