发布时间：2020-12-31 18:11
计算机数控（CNC）加工已被认为是能够生产具有高精度和可靠质量的制造工艺,并在低成本的高质量供应在制造业中起着至关重要的作用,也适用于用于加工零件的切削工具的制造。整体立铣刀是机械加工中最常用的切削刀具之一,用于复杂形状表面的加工。为了提高生产效率,必须组织高质量和快速生产的切削刀具,包括整体铣刀。立铣刀通过许多参数定义,如直径、螺旋角、后角、前角、齿数等。这些参数必须确保了切削过程的切屑流动和加工后工件所需的表面质量。要做到这一点,必须开发满足这些高要求的软件,具有良好的界面并且易于使用。在我的研究工作中,选择了整体立铣刀,开发的软件考虑了整体铣刀的几何特征,使其更容易制造。首先,查阅了该领域的研究现状,包括国内外许多研究人员的研究论文和科学著作,总结整理了定义整体立铣刀的基本几何参数。整体立铣刀其参数结构设计含义:为了保持整体立铣刀圆周切削刃、螺旋槽、端刃和排屑槽的基本结构之间的相对位置关系、刀刃的长度、直径,重要几何参数如螺旋槽、刀刃的前后角和螺旋角在数学上被参数化,使得它们可以在有限的范围内调整。刀具的前角影响加工中的切削力,容屑槽的形状和尺寸决定了刀具的刚性和切屑排出能力,并...
