PURPOSE:To achieve the automation in grinding of a diamond compact tool, etc., and to improve the accuracy by measuring the work including a scheduled grinding amt. and a grindstone contact position coordinate, performing grinding based thereon and performing the correction of the coordinate dimension as well. CONSTITUTION:When the abutting part 8 of a 1st touch sensor 3 is pushed by a work 2 in NC feeding, the tip of the touch sensor 3 is brought into contact with a grindstone 1, the coordinate dimension of this case, i.e., the dimension (b) of the notching completion position including the scheduled grinding amt. d of the touch sensor 3 and work 2 is detected and stored in the NC device memory. On the other hand, the dimension C of the positional coordinate where the work 2 is brought into contact with the reacted to a 2nd touch sensor 4 by the NC feeding is detected prior to the grinding and stored in the memory inside the NC device. If the actually ground amt. is taken d' when the notching is completed, the dimension C+ d', the aiming C+ d are compared and when the both are equal or the latter is exceeding the value of the former, the working is completed.
