Numerical control system

Abstract

Abstract PURPOSE:To perform machining with high accuracy about an optional programmed shape, by effecting four-axis rectilinear interpolation to execute rectilinear distribution and arc distribution. CONSTITUTION:When a rectilinear block is read by a tape reader TR, the read signal is discriminated by a decoder DEC to set a rectilinear instruction value in a register REG. At that time, a vector computed by a calculation circuit AR1 is set in another register R1. Each axis component is determined from the vector set in the register R1 and is then set in another register R2. The contents of the register R2 are read by a reading and processing circuit RE1 and applied to an interpolater INT to control the drive of motors MU, MV, MX, MY by rectilinear interpolation to perform rectilinear taper machining. In arc distribution, an arc is equally divided into minute segments and four-axis rectilinear interpolation is effected to perform machining.
