Optimization of Designing on Cutter Parameters of PCD Saw Blades by Simulation Analysis

Аннотация

The cutter parameters of PCD circular saw blades play a decisive role in the wood cutting process, they directly affect the machining surface quality and tool life. Simulation analysis of the cutting stress and deformation of PCD wood circular saw blades with different cutter parameters is carried out using the finite element method. The results show that the maximum shear stress of the PCD saw blade in cutting process are all in a safety range with safety coefficient of about 3.5–4.0, and the maximum displacement of PCD saw blades are about 4.8–4.9 µm in the axial direction and about 10 µm in radial and rotation directions. It was found that the best cutter parameters of the PCD circular saw blades are rake angle γ = 15° and rear angle α = 15°, in which the relative low stress of 58.9 MPa and relative smaller displacement of can be achieved.
