A HUMAN-MACHINE INTERFACE ADAPTED TO BE ASSOCIATED TO AN APPARATUS FOR WORKING PIECES, HAVING AN INSTRUMENT FOR PIECE DETECTION, FOR AUTOMATICALLY PROGRAMMING A PIECE WORKING CYCLE

摘要

An electronic-control apparatus (1) for machining workpieces, for example plates of natural or synthetic stone material, or plates of glass, or pieces of wooden material, comprises an operating head (8) movable above a working surface (3). The apparatus comprises an electronic control unit (E) programmable for moving the operating head (8) in such a way as to follow pre-determined paths, according to a pre-determined cycle, for machining a workpiece (L) positioned on the working surface (3). The apparatus further comprises a human-machine interface (HMI) for programming the electronic control unit. The human-machine interface (HMI) includes an instrument (12, 13; 15) for detecting information on the shape and dimensions of the workpiece (L). This instrument is associated to an electronic processing unit (14) adapted to process the information at output from the aforesaid detection instrument (12, 13; 15) and to transmit input data to the aforesaid electronic control unit (E), for automatic generation of a program for implementing the machining cycle.
