Organization of an NC program in HEIDENHAIN
Conversational format
A part program consists of a series of program blocks. The figure at
right illustrates the elements of a block.
The TNC numbers the blocks in ascending sequence.
The first block of a program is identified by BEGIN PGM, the program
name and the active unit of measure.
The subsequent blocks contain information on:
 The workpiece blank
 Tool calls
 Approaching a safe position
 Feed rates and spindle speeds, as well as
 Path contours, cycles and other functions
The last block of a program is identified by END PGM, the program name
and the active unit of measure.

Danger of collision!
After each tool call, HEIDENHAIN recommends always
traversing to a safe position from which the TNC can
position the tool for machining without causing a collision!
