Tak\u0131m malzemesi ne kadar sertse, a\u015f\u0131nma direnci o kadar iyi, sertlik o kadar y\u00fcksek, darbe toklu\u011fu o kadar d\u00fc\u015f\u00fck ve malzeme o kadar k\u0131r\u0131lgand\u0131r.

2. If the back angle increases, the strength of the tool edge decreases and the wear area of the flank increases gradually. When the tool’s back angle is too large, the cutting vibration is strengthened. The smaller the rear angle is, the longer the friction contact length between the elastic restoring layer and the flank is. It is one of the direct causes of the wear of the cutting edge and the flank. In this sense, increasing the rear angle can reduce friction and improve the machined surface quality and tool life.<\/strong><\/strong><\/p>\n\n\n\n
