A SENSOR FUSED OPEN ARCHITECTURE INTELLIGENT MACHINING PROCESS CONTROL AND MONITORING MODULE HAS BEEN DEVELOPED FOR MACHINE TOOLS. THE MACHINING PROCESS MONITORING AND CONTROL ALGORITHMS INCLUDE ADAPTIVE CONTROL OF MAXIMUM CUTTING FORCES OR SPINDLE MOTOR CURRENT PER SPINDLE REVOLUTION, IN-PROCESS TOOL BREAKAGE DETECTION IN MILLING, CHATTER VIBRATION DETECTION AND SUPPRESSION. THE ALGORITHMS ARE BUNDLED IN A DEDICATED DIGITAL SIGNAL PROCESSING BOARD AND COMMUNICATE WITH THE CNC VIA AVAILABLE STANDARD FUNCTIONS OPEN TO THE USERS. THE PRESENTLY DEVELOPED SYSTEM CAN BE INSTALLED TO ANY COMMERCIAL CNC SYSTEM WHICH HAS OR COMMUNICATES WITH AT/ISA BUS.
