Title:
PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2021186940
Kind Code:
A
Abstract:
To display on a display unit a remaining number of workpieces that can be processed with a processing grindstone.SOLUTION: A processing device for processing a workpiece includes: a processing unit that processes the workpiece by use of a processing grindstone; and a control unit 44 that controls each of composing elements. The control unit includes: a consumption amount calculation unit 60 that calculates an amount of consumption of the processing grindstone when the work-piece is processed with the processing grindstone; a total consumption amount calculation unit 64 that calculates, as a total amount of consumption, the total of the amounts of consumption of the processing grindstone; an average consumption amount storage unit 66 that stores, as an average amount of consumption, the average of the amounts of consumption of the processing grindstone for processing workpieces; a processable remaining number calculation unit 68 that calculates a remaining amount of a blade edge by subtracting the total amount of consumption from the limit amount of consumption of the processing grindstone and divides the remaining amount of the blade edge by the average amount of consumption to calculate a remaining number of workpieces processable with the processing grindstone; and a display control unit 70 that displays the processable remaining number on the display unit.SELECTED DRAWING: Figure 4
