APT programming

                   In general APT means“Automatically Programmed Tool”. The APT programming is done using the Cutter location (CL) points. APT can also be called as Cutter location File. APT programming can be classified into following below groups:

1) APT Geometry statements,

1)      Defining a point

2)      Defining a Line

3)      Defining a Circle

4)      Defining a Plane

2) APT Motionstatements.

3) APTPostprocessor statements.

When all these groups perform in a set then we have a complete program, Apt Geometry statements tells where the tool has to move, APT motion statement tells When and how the tool has to move will, APT postprocessor statements tells What tool has to move.

·         APT is also one of the languages that are output by many computer programs that produce CNC part programs directly from designs and drawings produced with CAD/CAM systems.

·         APT language is one of the computer languages designed to use with many NC machine tools.

·         APT was originally designed and used on mainframe computers and now it is available on mini- and microcomputers.

·         APT has also been recognised by the International Organization for Standardization (ISO) as a standardized language for NC programming.

·         APT is a very dynamic program and is continually being updated to use in CNC programming.

·         APT has the capability of programming the machining of parts in up to five axes, and also allows computations and variables to be included in the programming statements so that a whole family of similar parts can be programmed easily.

·         APT programing can be done by giving guide to the basic geometry andusing motion statements which is then converted by postprocessor to the machine readable G-codes and M-codes language.
