The article presents research results on the effect of cooling and lubrication on the cutting force in cutting off process of A11and C45 steel rods using different rake face shapes and cutting parameters. The aim of the investigation was to determine outcomes of elimination (dry cutting) or reduction (minimum quantity lubrication – MQL) of a cooling and lubricating fluid in the cutting off process. It has been concluded that the minimum quantity lubrication allowed decreasing the cutting force compared to dry cutting. The impact of eliminating or reducing the quantity of the cooling and lubricating medium on the cutting force in the cutting off process of both types of steel depend on the applied feed rate and cutting speed. Taking into account environmental reasons, the dry and MQL cutting off is advisable and highly justifiable.
