Title:
MUMERICALLY CONTROLLED WORK SYSTEM
Document Type and Number:
Japanese Patent JPS5968011
Kind Code:
A
Abstract:
PURPOSE:To judge whether a tool is outside of the shape of a work before machining, to move the tool at a high speed when the tool is outside of the shape, and to shorten the idle movement time of the tool by inputting the shape of the work previously before the machining and comparing the shape data with a work route. CONSTITUTION:The cylindrical work 12 is fixed to a chuck 10 which rotates around the rotating shaft Z of a lathe and its one end part is supported by the tip part 14a of a tail 14. When the work 12 is cut, a turret 16 is moved in a direction Z and the work 12 is cut by the tool 18. The shape before machining for this work 12 is inputted previously. This input shape data is compared with respective work routes l1-l4 to feed the tool 18 relatively slow in an actual work area shown by the routes l1-l4. Then the tool 18 is fed at a high speed in the idle movement area shown by dotted lines where the cutting is not performed, thus obtaining the final work shape 20.
