摘要： An improved cutting tooth configuration in which, unlike the conventional, straight line tool pattern with its constant tool rise, each tooth is incrementally advanced relative to the prior tooth by an amount that progressively decreases. This accounts for the variations in reaction force on the cutting teeth caused by workpiece deflections, so that the net thickness of material removed by each cutting tooth remains relatively constant. Instability and variation in the cutting force are thereby avoided, and tool wear is decreased.

摘要： The disclosure reveals a computer vision technique to measure flank and crater wear of a single point cutting tool. This direct tool wear measurement method uses a microscope mounted camera to acquire an image of the tool. Special lighting of a face of the tool shows contrast of the wear region in the image. The image analysis is based on an interactive procedure utilizing a general purpose image processing system. A computer program calculates ten parameters to characterize flank and crater wear.

摘要： A cooling system for an engine assembly includes an engine block that defines a coolant flow passage configured to carry coolant through the engine block. The engine block also defines an oil flow passage configured to carry lubricating oil through the engine block. The oil flow passage at least partially surrounds the coolant flow passage and is sufficiently adjacent to the coolant flow passage so that the lubricating oil flowing in the oil flow passage is cooled by the coolant flowing in the coolant flow passage by heat transfer through the engine block. The engine block may define ridges along the coolant flow passage that increase a surface area of the coolant flow passage to increase heat transfer capability. The engine block may define two such coolant flow passages, a first and a second coolant flow passage, positioned so that the oil flow passage passes between the coolant flow passages.

摘要： An engine block mold package includes a barrel crankcase core having a plurality of barrels on each of which a respective cylinder bore liner is disposed. Each cylinder bore liner includes an inside diameter that is tapered along at least a portion of its length to match a draft angle present on the barrels to permit removal of the barrel crankcase core from a core box in which it is formed.

摘要： A main bearing cap for an internal combustion engine has a longitudinally extending body defined in pan by parallel sides which terminate in first and second end portions. The bearing cap has a centrally located, semi-cylindrical bearing recess which cooperates with a corresponding recess in the engine crankcase to support journals of a crankshaft along a crankcase axis. The first and second end portions of the bearing cap include laterally outwardly extending flanged feet having end faces which mate with corresponding surfaces on the engine crankcase. The flanged feet operate against the engine crankcase to limit motion of the bearing cap body.
