The Numerical Control Kernel (NCK) unit is the key component of a CNC system and consists of a variety of modules that are sequentially executed in a synchronized schedule. In this chapter the code interpreter will be addressed. This is responsible for converting the part program and machine instructions into internal commands for NC. In order to understand the code interpreter the first thing is to understand the part program that is the input to the interpreter. After this, the structure and the functions of the code interpreter will be addressed in detail.
