摘要： There is provided an apparatus for predicting a tool life which reports a tool life ratio to an operator or a control device, when a remarkable change of work load values is detected. In a predicted life setting section 122, there is set a percentage of a quantity worked until the detection of the noticeable change of the work load values based on the workable quantity until the breakage of the tool which is regarded as 100%. A predicted residual work quantity calculating section 123 calculates a residual tool life value converted into a parameter at a point of time when an alarm is input from a work load monitoring section 121, on the basis of data of a work quantity accumulating section 120 and the predicted life setting section 122. A predicted residual work quantity outputting section 124 reports the residual tool life value to an operator or a control device. In consequence, when the remarkable change of the work load values has been detected, a ratio of the residual work quantity to the tool life can be reported to the operator or the control device.
