Abstract

PURPOSE: To perform machining while avoiding the interference of a ball end mill with a workpiece, by using a numerical controller to regulate a milling machine to control the position of the ball end mill relative to the workpiece.
CONSTITUTION: A ball end mill is caused to radially cut into a core and displaced in the direction of vertical axis of the core. At that time, the displacement of the end mill is predetermined on the basis of the coordinates (l,α) of the center θ of the cutting tool which are determined from compensatory values ΔX, ΔY, ΔZ and the coordinate value Y of the center Q of the tool. The values L, α are determined from relationships which are found out on the assumption that the cutting tool woued be cut off along a plane which contains the center of the tool and is perpendicular to an axis Z. A relative position determined from equations L= [(Y+Y)2+X2]1/2, α=θ+η+δ, η=tan-1Y+ΔY/ΔX, δ=π.ΔZ/P, where Y denotes the corrdinate value of a cutting point A, is numerically controlld to perform machining while avoiding the interference of the cutting tool with the workpiece.
