ABSTRACT

This paper presents results of research on effect of PCBN geometry insert on the surface roughness,

m ngid turning CNC for 2311 steel alloy after hardening Plane approach angle, rake angle, tod

nose radial are considered which are parameters influence on surfa ce roughness. Equations describe

the relationship between parameters with surface roughness are determined base on using planning
