Theory and Application of High-Efficiency and Accurate Processing of Roller Hole Shapes
Roller hole shape is a commonly used means in many industries such as food machinery, chemical machinery, paper machinery and other manufacturing processes, and its processing technology has directly affected the normal operation of the machinery and the quality of the product. It is suitable for the processing of complicated profiles. In order to improve the production of roller hole shape and ensure the product quality, American scholars have carried out a lot of research and obtained some effective results.
The principles of high-efficiency and precise processing of roller hole shapes include cutting machining and molding technology. Firstly. To cutting machining, it adopts the method of numerical control processing, which can accurately position the cutting tool and complete the processing of the hole in one time. Secondly. In addition to using the cutting method, the molding method for hole forming can also be adopted. This method is generally used by die casting and forging. It uses the mold to accurately process the hole shape. Furthermore, the tool can also take a certain reaction force to ensure the accuracy of the machined surface.
When machining the roller hole shape, the milling cutter is selected according to the shape of the hole. Generally, the selection of small milling cutter should be preferred. Choose reasonable milling cutter knife number according to the shape of the hole, which can reduce the processing time and improve the machining efficiency. The cutting speed and feed are also important factors in machining. If the cutting speed is too slow, it will cause severe vibration and affect the machining accuracy. In order to ensure the machining accuracy, the milling cutter can pass water-cooling to ensure the temperature during the machining process.
In order to achieve high-efficiency and precise processing of roller hole shape, it is necessary to cooperate with numerical control technology. The numeral control system has the algorithms of linear interpolation and circular interpolation, which can accurately calculate the machining points and coordinates of hole shape, and then coordinate with each machining motion. After all the machining points and coordinates are calculated, the machining path of the tool can be obtained. Finally, the movement of the tool can be tracked according to the machining path.
In addition to the above technology, the application of computer aided design (CAD) technology can also obtain high-precision roller hole shape. The CAD is the combination of engineering design technology and computer technology. Programs can be written to calculate the profile of the hole on the computer. After calculation, the profile and machining process can be obtained, and then the whole machining process can be operated in the numerical control machine.
In conclusion, high-efficiency and precise processing of roller hole shape can be completed by adopting the above methods and combining numerical control technology and CAD technology. With the development of technology, these methods and technologies can be further applied in other similar machining processes, which will further improve the machining efficiency and accuracy of roller hole shape.
