Three methods of workpiece coordinates establishing and tool compensating based on FUNUC 0iT NC system are presented in this paper.

The two methods of workpiece coordinates establishing and tool compensating based on FANUC 0iT NC system are presented.

Interpreter program design based on workpiece coordinate system;

It is an important item to set tool and establish workpiece coordinate system in NC machining operation.

it is important matter that setup workpiece coordinate system in reason,thus make the best of coordinate system of the NC system and machine worktable that realize automatic machining of workpiece.

It is an important step to determine the origin of part coordinate system in CNC operations.

To help the engineering-oriented men and students of vocational college master the process and principle of setting up part coordinate system for CNC machine,the paper describes the modes and processes of positioning of tool of different kinds of CNC machines.

Introduces the methods of seven points to calibrate tool coordinate frame and three points to calibrate coordinate frame of work-piece.

A method using three points to calibrate coordinate frame of work-piece on the basis of some sensor information is presented.

The Research on the Automatic Compensate of the Workpiece Coordinate at Horizontal Machining Center;
