<p>A spindle control method for a numerical control apparatus (CNC). A numerical control apparatus (1) is coupled to a PMC (2) through a bus A(8) and is coupled to a spindle speed controller through a bus B(9). The instruction from the numerical control apparatus (1) is sent to a spindle speed controller (3) over the bus B(9), and the instruction from the PMC (2) is sent to the spindle speed controller over the bus B(9) via the numerical control apparatus (1). The spindle speed controller (3) and the numerical control apparatus (1) is interfaced through a bus, thus contributing to simplifying the constitution without requiring any particular cables. <H0> ABSTRACT </H0> A spindle control system in a numerical control apparatus (CNC). A numerical control apparatus (1) and a PMC (2) are connected by a bus A (8), the numerical control apparatus (1) and a spindle speed control unit are connected by a bus B (9), a command from the numerical control apparatus (1) is sent to the spindle speed control unit (3) by the bus B (9), and a command from the PMC (2) is sent to the spindle speed control unit, via the numerical control apparatus (1), by the bus B (9). As the interface between the spindle speed control unit (3) and the numerical control apparatus (1) is bus-connected, a simplified arrangement can be realized without the need for special cables or the like.</p> |
