Abstract
Disclosed is a system for controlling a numerically controlled machine tool sysem from a PC type computer system of the kind using an 8088 microprocessor chip and 8-bit words. The system includes an inverter timing board which is inserted into the PC equipment for conditioning signals from the parallel port of the computer into signals having wave forms of selected time length comforting to the numerical control tape code which is acceptable by the numerical control equipment at the machine tool.

A system for sending control signals to a machine tool which is adapted to be responsive to signals conforming to numerical control tape code, said system utilizing signals output from a computer having a parallel port, said computer being adapted to store, process and send steady but strobable high and/or low bit signals in computer code comprising:
- (a) means for receiving parallel output bit signals from the parallel port of said computer;
- (b) means for receiving a strobe signal from the parallel port of said computer;
- (c) time delay means actuatable by said strobe signal for conditioning the steady by strobable high and/or low bit signals from the parallel port of said computer into conditioned square wave signals having wave forms of selected time length conforming to said numerical control tape code;
- and
- (d) means for transmitting said conditioned square wave signals to said machine tool.
