Hydropower forging is an important part of hydropower equipment, its quality and performance directly affect the operation efficiency and safety of hydropower equipment. The selection of cutting tools and the optimization of cutting parameters are important factors affecting product quality and production efficiency in the production process of hydropower forgings. In this paper, the methods of tool selection and cutting parameters optimization in the production of hydroelectric forgings are introduced respectively from two aspects: tool selection and cutting parameters optimization.
In the production process of hydropower forgings, the choice of cutting tools should be determined according to the material, structural characteristics and production process of the forgings. Here are some factors to consider when choosing a tool:
Choice of tool material: The choice of tool material should be determined according to the material of the forging. For example, for high hardness and high strength forgings, tool materials with higher hardness and better wear resistance can be selected, such as cubic boron nitride (CBN) or diamond.
Choice of tool structure: The structure of the tool should be determined according to the processing requirements and process characteristics of the forging. For example, for machining that requires a large feed, a tool with a large front Angle can be selected to reduce cutting forces and cutting heat.
Selection of tool geometric parameters: the geometric parameters of the tool include front Angle, back Angle, main deflection Angle, etc., should be determined according to the material and processing requirements of the forging. For example, for high hardness, high strength forgings, you can choose a smaller front Angle and a larger back Angle to reduce the cutting force and cutting heat.
In the production process of hydropower forgings, the optimization of cutting parameters can improve production efficiency and quality, reduce cutting force and cutting heat, and extend tool life. Here are some ways to optimize cutting parameters:
Feed speed optimization: feed speed is one of the important factors affecting cutting force and cutting heat. The choice of feed speed should be determined according to the material of the tool and the forging. For example, for forgings with higher hardness and strength, a lower feed speed can be selected to reduce cutting force and cutting heat.
Optimization of cutting depth: Cutting depth is also one of the important factors affecting cutting force and cutting heat. The choice of cutting depth should be determined according to the processing requirements and process characteristics of the forging. For example, for processing that requires a large cutting depth, a larger cutting depth can be selected to improve production efficiency.
Speed optimization: Speed is one of the important factors affecting the cutting speed and cutting force. In the choice of speed, it should be determined according to the material of the tool and the forging. For example, for forgings with higher hardness and greater strength, a lower speed can be selected to reduce cutting force and cutting heat.
In addition to tool selection and cutting parameter optimization, other considerations may also be included in the production process of hydropower forgings, such as process flow, cooling effect, etc. Here are some other considerations:
Process optimization: Process optimization can improve production efficiency and quality, reduce waste and unnecessary links in the production process. For example, advanced production processes and equipment can be used to reduce unstable factors in the production process and improve the stability of the production process.
Optimization of cooling effect: Optimization of cooling effect can reduce cutting heat and cutting force, extend tool life and improve product quality. For example, advanced cooling technology and equipment can be used to fully cool the cutting area, reduce the cutting temperature and reduce the cutting force.
Tool selection and cutting parameter optimization are important means to improve product quality and production efficiency. When choosing the tool, the material, structure and geometric parameters of the tool should be determined according to the material, structural characteristics and production process of the forging. When optimizing the cutting parameters, feed speed, cutting depth and speed should be determined according to the material of the tool and the forging. In addition, other factors such as process flow and cooling effect should be considered. Through reasonable tool selection and cutting parameters optimization, production efficiency and quality can be improved, production costs reduced and product quality competitiveness improved.
