PROGRAMMING

INTRODUCTION
This workbook provides basic programming principles necessary to begin programming the HAAS C.N.C. Lathe.
In a “CNC” (Computerized Numerical Control) machine, the tool is controlled by a computer and is programmed with a machine code system that enables it to be operated with minimal supervision and with a great deal of repeatability.
The same principles used in operating a manual machine are used in programming a CNC machine. The main difference is that instead of cranking handles to position a slide to a certain point, the dimension is stored in the memory of the machine control once. The control will then move the machine to these positions each time the program is run.
In order to operate and program a CNC controlled machine, a basic understanding of machining practices and a working knowledge of math is necessary. It is also important to become familiar with the control console and the placement of the keys, switches, displays, etc., that are pertinent to the operation of the machine.
This Haas lathe workbook can be used for both operator’s and programmer’s. It is meant as a supplementary teaching aid for the user of HAAS Lathes. The information in this workbook may apply in whole or in part to the programming of other CNC machines. It is intended to give a basic understanding of CNC programming and it’s applications. It is not intended as an in-depth study of all ranges of the machine use, but as an overview of common and potential situations facing CNC programmers. Much more training and information is necessary before attempting to program on the machine. For a complete explanation and an in-depth description, refer to the Programming and Operation Manual that is supplied with your HAAS lathe.
