Abstract: A vacuum system and apparatus extracts metal chips and cuttings away from the cutting area of a sawing machine. The system and apparatus is located on the previously cut surface end of the saw and includes rotatable bracketry to engage and disengage a vacuum nozzle from the end of a cut piece to extract metal chips and cuttings from the inside of hollow metal stock as the stock is being cut. Rotation of the bracketry is actuated by means of an electronic controller or other control circuitry.

Abstract: An improved method of automatic sawing employs a programmable automatic saw and a remotely located computer which provides additional control for the saw or a group of saws. The saw is equipped with a programmable controller that is capable of storing a series of jobs. The programmable controller allows an operator to run one saw job while contemporaneously programming another saw job. A third person, such an engineer or supervisor, may be programming an additional job or ranges of jobs for the saw while the operator is running and programming other jobs. The improved system provides control for a group of saws thereby assisting in the distribution of work flow, enabling efficient use of materials and improving inventory controls.
