This paper presents the results of theoretical analysis and experiment of rotary hydraulic servomotor which consists of a pilot valve and an axial piston motor.It is well known that oil leakage problem can not be ignored in an axial piston motor. Unlike in a linear motor (e.g. cylinder-and-piston type motor), there is considerable oil leakage not only between high and low pressure sides (internal leakage) but also between shell and each side (external leakage).To the authors' knowledge, there have been few papers describing theoretical analysis of rotary hydraulic servomotor taking the external leakage into consideration.In this paper the authors analyze servomotor taking its external and internal leakages into consideration and in this analysis they introduce a new method of approximation for the “load pressure vs. load flow characteristics” of pilot valve.The result of this theoretical analysis fairly well coincides with that of experimental result.From the result of the above mentioned theoretical and experimental researches, it becomes evident that the existence of external leakage is equivalent to an increase in internal leakage.

This study deals with contouring control system of machine tools, which uses electro-hydraulic pulse motors as its main part. First, the system's features are briefly given and the algebraic arithmetic type interpolator which is used in the system is described. Secondly, an analysis of the dynamic characteristics of thh electro-hydraulic pulse motor is given. Last, the error of the system connected to the machine tool is examined showing that the machining error will be greatly reduced by a proper use of the cutter's center path offset mechanism of the system.

The Construction and the operation of a computing numerical control system including a special purpose computer are explained.The features and the merits of this system are as follows;1) No preliminary calculations concerning the cutter offset are necessary for the programming. The mumerical informations on the cutter radius are given by dial setting on the operation panel of the equipment.2) Electro-hydraulic pulse motors are employed as the servo-elements to drive the machine-tool.3) All transistorized and extremely miniaturized.
