Cylinder processing the choice of cutting parameters
Engine block choice of cutting parameters including cutting speed, feed rate and feed rate option. Cnc milling machine As the processing equipment is used in high precision and rigidity of machine tools and high-speed machining centers in order to ensure the efficiency of cutting may be the appropriate choice of cutting a larger amount.
The main processing engine block surface plane and bearing bore, cylinder bore holes such as the processing, while the plane and bearing bore, cylinder bore of the processing method is mainly milling and boring, Cnc milling machine so the discussion here, the choice of cutting parameters are mainly milling and Boring choice of cutting parameters.
(1) milling the choice of the amount of usage the choice of milling milling effect is directly related to good or bad. Generally speaking, the choice of dosage milling principles: Face milling cutter should be as much as possible when you first take a larger milling depth and width of milling, and then select the larger milling rate of as much as possible. Milling in a specific amount of choice when many factors involved, but in general, rough milling large margin when the workpiece, processing requirements low, the main consideration of the durability of cutter; Fine Milling margin is small, high precision machining, improvement in the quality processing of primary consideration; In the engine block of the milling process, the use of machine tools as having a high stiffness, high-speed machine tools, big power, rigidity is good, so has chosen the relatively large amount of cutting
(2) boring dosage amount of choice options under the rough finishing process varies. Rough, the selection of a larger depth of cut, finish, the selection of a smaller depth of cut. Depth of cut determined later, as cutting a large amount of use. In the cutting depth and feed rate after the selection ?=can be a reasonable tool to ensure durability under the conditions of use calculations or look-up table method to determine the cutting speed. In general, the rough, choose a lower cutting speed, finishing, the selection of a higher cutting speed. In the engine block boring process, the selection of machine tools as having a high stiffness, high-speed machine tools, big power, good rigidity; tool for foreign advanced tools, high quality, rigidity is good, so has chosen the relatively large amount of cutting.
Through the engine block of the structure and process characteristics of the analysis, discusses the engine block machining process design principles and basis of the choice of cutting parameters, and U-turn at high speed milling and boring, for example, design, Cnc milling machine analysis of the engine cylinder body of high-speed milling and turnover boring process, and in the processing need to pay attention to.
