3.1 BASIC INTRODUCTION
This section provides the basic programming and operation principles necessary to begin operating the ma-
chine. The remainder of this manual is divided into more detailed Programming and Operation sections.
In an îš“NCîš” (Numerically Controlled) machine, the tool is controlled by a code system that enables it to be
operated with minimal supervision and with a great deal of repeatability. îš“CNCîš” (Computerized Numerical
Control) is the same type of operating system, with the exception that the machine tool is monitored by a
computer.
The same principles used in operating a manual machine are used in programming an NC or 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.
The operation of the VF-Series Vertical Machining Center requires that a part program be designed, written, and
entered into the memory of the control. The most common way of writing part programs is off-line, that is, away
from the CNC in a facility that can save the program and send it to the CNC control. The most common way of
sending a part program to the CNC is via an RS-232 interface. The HAAS VF-Series Vertical Machining Center
has an RS-232 interface that is compatible with most existing computers and CNCîš’s.
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 manual can be used as both an operatorîš’s manual and as a programmerîš’s manual. It is intended to give a
basic understanding of CNC programming and itîš’s applications. It is not intended as an in-depth study of all
ranges of 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.
The programming section of this manual is meant as a supplementary teaching aid to users of the HAAS
Vertical Machining Center. The information in this section may apply in whole or in part to the operation of other
CNC machines. Its use is intended only as an aid in the operation of the HAAS Vertical Machining Center.
