Abstract: Acording to the characteristics of PDC bit cutting process and the relevant metal cutting theory, this paper gives ercise definition of working angles, i.e. actual backrake and actual siderake of PDC cutter, derives their urate calculation formulas, and analyzes the law of the effects of structural parameters on them, which is of at importance to the design, cutting force calculation and performance perdiction of PDC bits.
