Dongguan CNC machining mechanical parts processing material process performance _ as a discipline, mechanical parts processing from the overall design of mechanical design, comprehensive application of the results of various related disciplines, study the principle, structure, characteristics, application, failure form, bearing capacity and design procedures of various basic parts;
To study the theory, methods and guidelines of designing basic parts, and thus establish a theoretical system combining practice in this discipline, which has become an important basis for research and design machinery.
Since the appearance of machinery, there are corresponding mechanical parts.
But as a discipline, mechanical parts are separated from mechanical construction and mechanics.
With the development of the machinery industry, the emergence of new design theories and methods, new materials and new processes, mechanical parts have entered a new stage of development.
Finite element method, fracture mechanics analysis, elastic fluid dynamic pressure lubrication, optimization design, reliability design, computer aided design, Dongguan CNC machining system analysis and design methodology, etc, it has been gradually used in the research and design of mechanical parts.
Better realize the integration of various disciplines, realize the combination of macro and micro, explore new principles and structures, adopt more dynamic design and precise design, and make more effective use of electronic computers, further development of design theories and methods is an important trend in the development of this discipline.
The process performance of mechanical parts processing materials the processing performance of materials mainly includes casting, pressure processing, cutting processing, heat treatment and welding.
The quality of the processing technology directly affects the quality, production efficiency and cost of the parts.
Therefore, the process performance of CNC machining materials in Dongguan is also one of the important bases for material selection. 1.
Casting performance: Generally speaking, alloys with low melting point and small crystallization temperature range have good casting performance. For example, the alloy is the best in composition and casting. 2.
Pressure Processing performance: refers to the ability of steel to withstand cold and hot deformation.
The sign of good cold deformation performance is good molding, high surface quality, and not easy to produce cracks;
The sign of good thermal deformation performance is good ability to accept thermal deformation, high oxidation resistance, large temperature range of deformation and small thermal brittle tendency. 3.
Cutting performance: Tool wear, power consumption and surface finish of parts are signs for evaluating the cutting performance of metal materials and one of the important bases for reasonable selection of materials. 4.
Weldable: Measuring the welding performance of the material is marked by the strength of the weld area not lower than that of the matrix metal and no cracks. 5.
Heat treatment: refers to the behavior of steel during heat treatment.
