Ultra-dense tooth face milling cutter and design method thereof

Abstract

The invention discloses an ultra-dense tooth face milling cutter and a design method thereof. The ultra-dense tooth face milling cutter can solve the problem that the existing milling cutter has low cutting efficiency and alow processing precision in processing on a material having high processing difficulty. In design, the number of milling teeth is used as an independent variable and according to influences of structure parameters and cutting parameters, under the premise of strength maintenance, the most appropriate number of the milling teeth of an ultra-dense tooth face milling cutter is obtained so that efficiency is improved, a loss is reduced and a processing precision is improved. The number of the milling teeth is greatly increased so that processing efficiency is greatly improved. Through appropriate decreasing of a feeding amount of each one of the milling teeth, the feeding amount adapts to the number of the ultra-dense milling teeth so that a cutting force on each one of the milling teeth is reduced, blade wear is reduced, and surface quality of a processed workpiece is improved. Under the two influences, the ultra-dense tooth face milling cutter obviously improves processing efficiency. The ultra-dense tooth face milling cutter has high cutting efficiency and precision, prolongs a milling cutter service life and reduces a processing cost.

Description

technical field [0001] The invention belongs to the technical field of machining, in particular to an ultra-dense tooth face milling cutter and a design method thereof. Background technique [0002] Difficult-to-machine materials, such as titanium alloys and nickel-based alloys, have been widely used in aerospace, energy and power, automotive high-speed rail and other fields due to their advantages such as high strength and light weight. The rate is low, and it is more difficult to process than conventional materials. Therefore, the processing efficiency of the current conventional structural tools is low, the tool wear is serious, and the surface quality is often unstable. One of the main reasons is that due to the small number of teeth of conventional surface milling cutters, to achieve a certain cutting speed and feed rate, the feed rate per tooth must be relatively large, so the cutting capacity and cutting force per tooth will be relatively large. big. Taking the Sand...
