CATIA Prismatic Machining -- TABLE OF CONTENTS

Designing and drawing parts is an important part of any company process. However, just
designing the part does not make the airplane, automobile or any other product leave the
assembly line. The parts for the assemblies must be manufactured. The manufacture of
three axis machine parts will be the emphasis of this course. It will be assumed that you are
proficient in the Part Design, Sketcher, and Assembly Design workbenches. If you feel your
skills are not what they should be, or if you have trouble in some sections of this manual,
you may want to look back at your Part Design and Sketcher or Assembly Design books for
review.
Types of NC Machines
There are many different types of CNC machines used in production lines all over the
world. The prismatic machining portion of CATIA V5 concentrates on a few different
types. Those types will be highlighted here, although not all machine types will be used in
programming.
Three Axis Machines
Three axis machines are most commonly used for simple parts. Three axis machines come
in two styles, vertical and horizontal machining centers. Vertical machines have the tool
axis locked along the Z axis. The X axis generally points the length of the table, while the
Y axis runs forward and aft on the table. Several tools are usually carried in a carousel near
the head of the machine.
