Abstract
Official abstract text for this publication.
A controller of a cutting apparatus includes: a storage section configured to preliminarily store as a threshold an arbitrary value based on a load current value of a motor detected when a cutting blade is rotated at a predetermined rotational speed while supplying a predetermined quantity of cutting water in a state in which a cutting water supply nozzle is positioned in an appropriate position; and a judgment section configured to judge normality or abnormality according to the result of comparison between a load current value detected when the cutting blade is rotated at the predetermined rotational speed while supplying the predetermined quantity of cutting water and the threshold stored in the storage section.
First claim
Opening claim text (preview).
What is claimed is: 1. A cutting apparatus comprising: cutting means which includes a spindle supported in a rotatable manner, a motor for rotationally driving the spindle, a cutting blade mounted to a tip portion of the spindle, and a cutting water supply nozzle for supplying cutting water to the cutting blade; load current value detecting means for detecting a load current value of the motor; and control means for controlling the cutting means and the load current value detecting means, wherein the control means includes: a storage section configured to preliminarily store as a threshold an arbitrary value based on a load current value detected by the load current value detecting means when the cutting blade is rotated at a predetermined rotational speed while supplying a predetermined quantity of cutting water in a state in which the cutting water supply nozzle is positioned in an appropriate position; and a judgment section configured to judge normality or abnormality according to a result of comparison between a load current value detected by the load current value detecting means when the cutting blade is rotated at the predetermined rotational speed while supplying the predetermined quantity of cutting water and the threshold stored in the storage section. 2. The cutting apparatus according to claim 1 , wherein the threshold is stored in the storage section on the basis of device data for processing of a workpiece.
