IPC: G01B7/28
Filed: 1974-04-29
Abstract: 1470669 Measuring and control arrangements; copy milling MITSUBISHI JUKOGYO KK 29 April 1974 18697/74 Headings B3B and B3K [Also in Division G1] A numerical-control propeller-milling machine has a ram 3a carrying a head 3 for a milling cutter, a numerical control system for controlling the position of the head and apparatus for measuring manufacturing errors of the blade surface of a propeller when mounted in the machine. This apparatus includes a detecting head 1 mounted on the head 3 and operable to sense the blade surface and a counter 5 connected to the detecting head and to receive control pulses from the numerical control system for feed movement of the ram. When the probe 12 of head 1 contacts the blade surface during descent of the ram a signal from differential transformer 8 gates the counter to start counting pulses. The control programme is such that the ram descends to a position R 50 mm. below the design surface Q and the counter is preset to - 50 mm. Thus, if the count from the instant the probe touches the blade at P is say (50 + α) mm. then α mm. is the value of the deviation of the actual surface P from the design surface Q. The position of the head 1 in the horizontal plane is determined by the numerical control tape before the ram is lowered. If the deviation a lies outside + 50 mm. the printer 5 prints out a blank for the value corresponding to the horizontal coordinate obtaining.
