Abstract
Abstract Laser material working operations are accurately accomplished by an extremely rigid construction of the optical supporting bed and the material handling frame in combination with accurately machined locator pins and holes for preventing relative movement between the bed and frame due to shocks, vibrations and the like generally perpendicular to the laser beam, and resilient vibration isolating pads supporting the weight of the thus unitized bed and frame structure. The elongated bed if a rigid box beam and the stationary portion of the material holding frame is a one pieced steel casting. The locator holes are drilled and reamed in the frame for a force fit with the locator pins, are drilled and reamed in the bed for a tight slip-fit with the locator pins, and extend axially parallel with the laser beam. Threaded fasteners extending through over size holes secure the bed and frame together and separately to the floor through the intermediary of the resilient pads. The bed is provided with a single piece slide rail for carrying thereon the laser producing means, a focusing lens, a diverter for selectively diverting the entire laser beam to be dissipated in a heat sink between operations for allowing continuous laser production, and a partially silvered mirror for reflecting a minor portion of the beam to an instrument to produce a reading of the laser beam intensity. The material is held adjustably on a vertical carrier provided by means of two columns adding to the rigidity of the vertical carrier and the stationary frame.
