2.1 Summarization of CNC Programming

Definition of Machining File

Composed of a series of instructions written in a programming language which is specially used

for CNC device, a machining file will be translated into motion actions to control the machine tool by

CNC device. The most commonly used storage mediums are punched tape and disk.

Creation of Machining File

As shown in Fig. 2-1 below, a machining file can be created by traditional manual programming

or CAD/CAM application (Such as the popular MasterCAM application).

Machine Tool Coordinate Axes

To simplify programming and guarantee the generality of program, this manual has standardized

the naming of coordinate axes and the direction of CNC machine tool. Linear feeding coordinate axes
