The part program is a sequence of instructions, which describe the work, which has to be done on a part, in the form required by a computer under the control of
computer numerical control
Numerical control (also computer numerical control, and commonly called CNC) is the automated control of machining tools (such as drills, lathes, mills, grinders, routers and 3D printers) by means of a computer. A CNC machine processes a pie ...
(CNC) software. It is the task of preparing a program sheet from a drawing sheet. All data is fed into the CNC system using a standardized format. Programming is where all the machining data are compiled and where the data are translated into a language which can be understood by the control system of the machine tool.
The machining data is as follows :
# Machining sequence classification of process, tool start up point, cutting depth, tool path, etc.
# Cutting conditions, spindle speed, feed rate, coolant, etc.
# Selection of
cutting tools
In the context of machining, a cutting tool or cutter is typically a hardened metal tool that is used to cut, shape, and remove material from a workpiece by means of machining tools as well as abrasive tools by way of shear deformation. The majori ...
