Title:
COPYING CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/1982/000966
Kind Code:
A1
Abstract:
A copying control system in which the direction of pick feed is determined according to a copy travel direction signal (VTD) based on the output of a phase discriminating circuit (PD) and the direction of pick feed input from an input unit. The pick feed is driven by a profile copy, so that the plane of the pick feed can be in the X-Y plane in the case of copying working along a semi-spherical model or the like. The copy travel direction signal (VTD) designates that the direction of tangent velocity is +90 or -90 to the direction of the normal line, and then, according to whether the copy travel direction signal (VTD) is "0" or "1", the polarity of a delivered tangent direction velocity signal (VT) is inverted. A gate circuit (GC) selects output-amplifier circuits (DRX, DRY, DRZ), the outputs of which drive motors (MX, MY, MZ), respectively. Thus, in the case of copying a semi-spherical model, the plane of pick feed corresponds to that of profile copying, i.e., is in the X-Y plane.
