Correct Answer - Option 4 : Douglas T Ross

The correct answer is Douglas T Ross.

  • APT stands for Automatically Programmed Tool.
    • It was developed by Douglas T Ross.
    • It is a language that defines the tool path with respect to the part geometry and often forms the basis for post-processor generated NC files.

  • The APT programming language is a language for defining tool paths on CNC machines.
  • The APT language consists of four types of statements:
    • Geometry statements will be used to specify the elemental features defining the part shape
    • Motion statements are used to specify the path taken by the tool
    • Post-processor statements control the machinery, controlling coolants as well as the feeds and speeds.
    • Auxiliary statements complete the picture, specifying the part, required tools, etc.
