为了保证刀具最佳切削性能,圆锥形(或笔状)硬质合金模具立铣刀的螺旋槽是按等螺旋角设计的。即要求锥形面刀刃上各点的螺旋角相等,使刀刃上各点的前角相等。本文论述的非圆齿轮传动法,是磨削此类刀具的螺旋槽刃的一种方法。根据圆锥形立铣刀等螺旋角螺旋槽形成原理,我们建立了此方法的数字模型,并找出加工原理和加工该刀具等螺旋槽刃磨床的传动原理。并将通用的非圆齿轮设计计算微机化,圆而大大提高设计及计算的速度和精度。这就为非圆齿轮法加工等螺旋角圆锥形模具立铣刀的齿槽刃磨削机床的设计提供了可靠的理论根据。
In order to ensure the best cutting tool performance, conical (or pen) carbide cutter end mill spiral groove is designed according to the same helix angle. That is, the taper angle of each point on the blade must be equal, so that the rake angle at each point on the blade is equal. The non-circular gear drive method discussed in this article is a method of grinding the helical flute edge of such a tool. According to the spiral helix groove forming principle such as conical end mill, we set up a digital model of this method and find out the machining principle and the transmission principle of the helical grooved grinding machine for machining the tool. And general non-circular gear design and calculation of computer-based, and greatly improve the design and calculation speed and accuracy. This provides a reliable theoretical basis for the design of the tooth edge grinding machine tool of non-circular gear machining helical conical die end mills.
