Correct Answer - Option 2 : in CAM for NC machine tools
Explanation:
The most widely used part programming languages are APT and COMPACT II. APT stands for Automatically Programmed Tools
- It is a high-level computer programming language used to generate instructions for numerically controlled machine tools
- The first prototype of the APT system was developed at MIT in 1956.
- The program was developed further by the cooperative efforts of 21 companies, sponsored by the Aerospace Industries Association (A I A) with assistance from MIT.
- APT can be considered as a CAM system based on a special-purpose language.
- It was created to simplify the task of calculating geometry points that a tool must traverse in space to cut the increasingly complex parts required in the aerospace industry.
It was a direct result of the new CNC technology becoming available at that time and the daunting task that a machinist or engineer faced calculating the movements of the CNC for the complex parts for which it was capable.
Machining specification:
-
APT has simplified the programming tasks in a great deal, providing a standard tool for all CNC programs is another reason for APT to exist
- ATP program can be used on a particular CNC machine.
