Sovietast Europoan Production of Hultiaxis Numerical Control Units

Main Points

The USSR ia the only Communiat country that la known to be producing,xis NC control units. The USSR produces two models, both hardwired. | [

Hungary blaims that two of its models, both softwired,xis capnbili y. Only one model, which uses clandestinely acquired US microprocessors, has been demonstrated operatinq in three axes; its production tftatus is nothere is no evidence that! either model is being used operationallyxis mode__with any Hungarian NC machine tools.

Poland is in the process of importingfor the productionxia unite. As far as can be determined, production has not yet begun. Indeed, all of the produc-

tion technology may not yet havecquired. ,Q

Czechoslovakia claims to bexis units, but their own literature shows that the unite forxis capability is claimed, arexia units.

The USSR hasew controllers capable ofxis control. Hungary claims that its basicxis controller is expandablexes of control, but there ia no hard evidence thatxis controllers have actually been built. ;Q

Thus, annual Soviet production of multiaxisxes) NC control units is lesshat of the United States. For all practical purposes, Sovietrepresents the total productionxis (and above) NC controllers in all Communist countries. ([

The USSR began producing a. fewxis contouring machine tools and control units Those were open-looped systems capable of linear, but not circular, interpolation.

, the USSR began serial productionow generationxis hardwired NC units. These units, 1 usetypes of low density integrated circuits (ICs) and represent current Soviot state-of-the-art in numerical control technology. Work is underway to devolop new NC devices based on higher density ICs including LSI (Large scale integration) but serial production of such NC controllers is not imminer.t. We expect that12 will continue to be the mainstay of Soviet production for the next several years.

1 is an open-loop system;2 issystom. As far as we can determinematerial, the open-loop system is in

xore common use than the closed-loop system. xis milling machines observed in the literature utilize1 open-loop system, whereas the use of the2 is rarely observed. We conclude that, of,these two types of controllers, the Soviets make mostly |

Closed-loop numerical control systems are rare because the USSR has encountcre'i problems in the serial production of the high quality subcomponents, namely transducers and rcsolvora, used in theirsystems. t least, those components were limportod. They may still be imported for wo havetrd evidenco that they are being produced.
