非标产品的插齿刀规格多面杂,每个规格都准备专用滚刀,既不经济,又不及时。当代用滚刀按相同模数和压力角进行计算,而在现有的滚刀中选不到合适的代用滚刀时,可采用变模数变压力角滚刀进行代用计算,达到尽可能少地减少二类工具——专用滚刀的设计和制造的目的。这一方法应用在我厂特殊订货的插齿刀生产中获得满意的切削效果和经济效益。 Non-standard products, shaper specifications Multi-faceted miscellaneous, each specification are prepared for hob, neither economical nor timely. Contemporary hob with the same modulus and pressure angle calculation, and in the existing hob can not choose a suitable alternative hob, you can use variable modulus variable pressure angle hob alternative calculation to achieve as little as possible to Reduce the second-class tools - the purpose of special hob design and manufacture. This method is used in our factory special orders shaper cutter production to obtain satisfactory cutting results and economic benefits.
