Abstract
A system and method for reducing kerf loss and controlling the tension and lateral vibration of an internal diameter saw blade by controlling the temperature of the blade while it is still rotating. The blade temperature is controlled by regulating the temperature of the cutting fluid flow associated therewith. In one embodiment blade tension is periodically measured and, when the tension falls below a predetermined limit, the temperature of the cutting fluid stream is decreased for a period of time until the tension increases to a preselected value.
Claims5
A method for controlling the tension of an internal diameter saw blade while sawing an object, comprising the steps of:
- directing a stream of fluid onto the cutting edge of said saw blade before said blade enters the object being sawed, wherein some of the fluid enters the cutting region;
- measuring the tension of said saw blade;
- and
- regulating the fluid temperature responsive thereto.
A system for controlling the tension of an internal diameter saw blade while sawing an object, comprising:
- means for directing a stream of fluid onto the cutting edge of said saw blade before said blade enters the object being sawed, whereby the fluid is carried into the cutting area;
- means for regulating the temperature of said fluid to control blade tension;
- and
- means for measuring the tension of said saw blade coupled to said regulating means, wherein said regulating means is responsive to said measuring means.
