Abstract
A workability detection method for a workpiece consisting of the steps of cutting a workpiece, based on specified cutting conditions, detecting the cutting resistance during the cutting operation, or the cutting time or the amount of tool wear to make a cut up to a specified position of the workpiece, or the feeding position of the cutting tool on a workpiece or the amount of processing of the cutting tool after a specified cutting time and comparing the detected data with corresponding data which is stored in a data base.
Claims18
A workability detection method for cutting a workpiece, comprising the steps of:
- cutting a workpiece up to a certain position as a result of which the load on a blade of the cutting machine is kept relatively small;
- detecting the cutting resistance during the cutting operation;
- comparing the detected data with back-up data which has been previously obtained and stored in a data base of a data storing means for the workpiece cut by the same type of blade;
- and
- judging workability of cutting by determining whether the detected data is within a predetermined range of values stored in the database.

A cutting method by means of a cutting machine on a workpiece comprising the steps of:
- cutting a workpiece to a certain position as a result of which the load on a blade of the cutting machine is kept relatively small;
- detecting a miscut amount of the workpiece by a miscut detection means during said cutting;
- comparing, when the blade reaches the said position, said detected miscut amount with a miscut limiting value previously obtained and stored in a data base for the workpiece cut by the same type of blade and determining whether or not the blade has reached a miscut end-of-life;
- selecting an appropriate cutting condition by judging the workability of cutting of the workpiece when continuous cutting is possible, and proceeding in cutting the workpiece further up to a next certain position, and
- replacing the blade at its end-of-life with a new one when the blade reaches its miscut end-of-life during the above steps.
