<p>A cutting tool is monitored on-line by measuring the heat generation rate at the cutting edge and relating this to the condition of the cutting edge. A flow of fluid coolant contacts the back surface of the cutting tool and the coolant temperature rise is measured during the machining process. The temperature difference and its rate of rise or fall is a direct indication of the heat generation rate and is related to tool conditions such as excessive and rapid wear and breakage. In the case of inserts, coolant channels are formed in the reusable seat, and tool holder channels provide for flow of coolant to the seat.</p> |
