#CMT# #/CMT# The method involves determining that whether a path of turbulent flowing cooling lubricant or compressed-air radiations is not deflected by a broken tool or by a workpiece, where the workpiece is incompletely processed by the broken tool before the impact of the turbulent flowing cooling lubricant or compressed-air radiations. Changed vibrations and/or acoustic waves are measured and compared with threshold values, where the vibrations are developed at a vibration sensor (8a) that lies in a driving direction of the cooling lubricant or compressed-air radiations. #CMT#USE : #/CMT# Method for detecting break-condition of a machine tool of an automatic lathe. #CMT#ADVANTAGE : #/CMT# The method allows for detecting the deviation of the test radiations or compressed air by the tool or the workpiece by using a blockage-insensitive and durable device, without requiring any special additional mechanical devices for producing pulsating radiations, and flexible switch. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a machine tool. 1 : Spindle housing 2 : Tool retainer 4a : Cooling lubricant supply pipeline 4b : Compressed air supply pipeline 8a : Vibration sensor. |
