Action Of a Pair Of Mating Involute Teeth Let a and b be the base circles of a pair of mating involute gears. Line CD is a common tangent to the base circles. while b is the line of centers assume that CD is part of a string being unwound from A and wound upon B, while A and B rotate together in such a manner that string CD remains taut at all times. When A and B start to rotate, point C on the string will leave
The manufacturing(or production) process of a factory, in a broad sense, is the sum total of separate processes involved in the conversion of sum total raw materials or semi-finished products into final as far as products. AS far as a factory is concerned, its blank products can be blanks, finished parts
Surface quality is another aspect of machining accuracy. It consists of the surface finish and the physic mechanical state of the surface layer. It affects the proper functioning and service life of the parts Surface Finish Machining accuracy is expressed quantitatively in machining error. Surface finish is expressed quantitatively in surface roughness. The surface roughness on a machined workpiece surface is caused primarily by the geometrical factors(cutting tool geometry and cutting
Almost all research papers are expositions. The word exposition quite literally means to set forth a subject. It appeals to the understanding and it is the most common kind of writing, for it is applicable to any task that challenges the understanding--the definition of a word the way to a street address the structure of a plant, the mechanism of a watch, the cause of a historical event the meaning of a philosophy
The Lathe And Its Construction A lathe is a machine tool used primarily for producing surfaces of revolution and flat edges. Based on their purpose, construction, number of tools that can simultaneously be mounted and degree of automation, lathes-or, more accurately, lathe-type machine tools-can be classified as follows:
