摘要
【目的】采用硬质合金单齿柄铣刀铣削三聚氰胺浸渍纸贴面刨花板,对比不同铣削参数对刨花板铣削质量和铣削力的影响,为刨花板优质铣削加工利用提供理论依据。【方法】以刀具前角、铣削线速度、铣削深度为自变量,设计单齿柄铣刀铣削试验,对比不同铣削参数的铣削结果,研究刀具前角、铣削线速度、铣削深度对刨花板铣削质量和铣削力的影响;采用回归分析确定各铣削参数的显著性,建立铣削过程中铣削力和表面粗糙度的数学模型,通过响应优化确立最佳铣削参数范围并进行试验验证。【结果】1)刨花板铣削表面粗糙度随刀具转速增大而减小;2)铣削力随刀具前角增大而减小,随铣削线速度增大而减小,随铣削深度增加而增大;3)刀具前角、铣削线速度和铣削深度对切向铣削力和铣削质量的影响具有统计学意义,刀具前角、铣削线速度和铣削深度的交互作用对切向铣削力和铣削表面粗糙度具有显著贡献;4)当刀具前角、铣削线速度、铣削深度分别为5°、9.42 m·s^(-1)、1.5 mm时,可在保证铣削效率的基础上有效减少加工过程中的能耗、提高表面质量。【结论】刀具前角、铣削线速度、铣削深度等铣削参数对刨花板铣削质量和铣削力均有一定影响,这些参数可用于贴面刨花板材料的工业生产,以获得更高的生产效率。
【Objective】To compare the effects of different milling parameters on the milling quality and milling force of particleboard by milling melamine impregnated paper veneer particleboard with a carbide single tooth shank milling cutter,and to provide a theoretical basis for the utilization of particleboard quality milling processing.【Method】The effect of tool front angle,milling line speed and milling depth on the milling quality and milling force of particle board was investigated by comparing the milling result of different milling parameters with a single-shank milling cutter using tool front angle,milling line speed and milling depth as independent variables;regression analysis was used to determine the significance of each milling parameter,and a mathematical model of milling force and surface roughness during the milling process was established.The optimum range of milling parameters was established and verified by test.1)The surface roughness of particle board milling decreases with increasing tool speed;2)The milling force decreases with increasing tool front angle,decreases with increasing milling line speed and increases with increasing milling depth;3)The effects of tool front angle,milling line speed and milling depth on tangential milling force and milling quality are statistically significant,and the interaction of tool front angle,milling line speed and milling depth has a significant effect on tangential milling force and milling surface roughness.4)When the tool front angle,milling line speed and milling depth are 5°,9.42 m·s^(-1)and 1.5 mm respectively,the energy consumption in the machining process can be effectively reduced and the surface quality improved on the basis of ensuring the milling efficiency.【Conclusion】The milling parameters such as tool front angle,milling line speed and milling depth have certain influence on the milling quality and milling force of particle board,and these parameters can be used in the industrial production of veneered particle board materials to obtain higher production efficiency.
