A system for control of movement of a cross sled which follows movement in an X-Y coordinate system according to a stored program, and for extending or shortening the path of movement either in the X-direction or Y-direction, or both directions.

Numerically controlled pattern cutting machine for glass panes

Method for correcting the control program of an automatic glass cutting machine including the steps of adding in counters signal pulses representative of travel of a scanning head in X and Y directions, checking the counter totals at the starting and end points of travel of the scanning head and introducing pulses in the program to bring the counter totals to a zero value. A device for correcting the control program of an automatic glass cutting machine having counters for adding signal pulses representative of travel of a scanning head in X and Y directions and a pulse generator for each counter which may put a required number of pulses into memory to bring the total count in the counters to zero at the completion of travel of the scanning head.

Process and apparatus for the correction of the control program of an

A form-cutting machine is disclosed for cutting a form in a flat surface of a sheet of material such as glass in response to a numerical control signal, the shape of the form being determined by the numerical control signal. The form-cutting machine comprises a frame, sheet-support means for supporting the sheet of material to be cut, an X-direction carriage-positioning assembly, a Y-direction carriage-positioning assembly, and a tool carriage having a cutting tool mounted on it so that the cutting tool can be positioned in a plane in which the cut is to be made. Each carriage-positioning assembly includes a carriage support member which extends generally perpendicular to a direction of motion, two guide members fixed to the frame which are spaced apart from one another and extend generally parallel to the direction of motion, and two sliders connected to ends of the carriage support member and slideably mounted on the two guide members. Each carriage-positioning assembly also includes a drive motor fixedly secured to the frame for moving the carriage-support member and toothed-belt means for connecting the drive motor and the carriage support member so that motion produced by a motor is imparted to the support member with substantially no slippage. The tool carriage is slideably mounted on the two substantially perpendicular carriage-support members, so that moving the carriage support members causes the cutting tool to move in a plane. The form-cutting machine further comprises circuit means connected to the drive motors so that the carriage support members and, consequently the tool carriage, are positioned in response to the numerical control signal.

Numerically-controlled form-cutting machine

An electric control system for a numerically-controlled form-cutting machine is disclosed. The form-cutting machine has two drive motors for moving a cutting tool respectively in an X direction and a Y direction. The control system comprises X-channel and Y-channel program-encoding means for encoding a program for numerically controlling the motion of the cutting tool in the X and Y directions respectively. The control system further comprises a magnetic-tape unit, for example, a cassette recorder, which can record the encoded programs on two tracks of magnetic tape. The control system further comprises X-channel and Y-channel program-decoding means for converting the signals played back from the magnetic-tape unit into signals suitable for controlling the motion of the cutting tool. The control system also includes conductive means interconnecting the components of the system.
