The Effects of Machining Parameters on Measured Temperatures and Energy Partition in Circular Sawing of Granite

Article Preview

An investigation is reported of the temperatures in the sawing of granite with a circular sawblade under a wide range of machining parameters including cutting fluids and cutting modes. Temperature responses in the sawing contact zone were measured using a foil thermocouple. The measurement was subsequently used to analyze the influence of operating parameters on the sawing temperatures and the energy partition. For either down-cutting or up-cutting, either with cutting fluids or without cutting fluids, the temperatures in the sawing zone were found to increase with depth of cut, sawblade speed, and workpiece speed. The maximum temperature in the sawing without cutting fluids was found to be up to 400°C whereas it was reduced to around 250°C while using cutting fluids. The energy partition conducted to the workpiece is about 7% ~10% in dry sawing and about 2% ~5% in wet sawing.
