摘要： PURPOSE:To enable increase of an open-loop gain and to prevent the occurrence of an error in positioning, by a method wherein, in a machine tool, the inertial reaction force of a moving body is burdened by a second drive device, and resilient displacement of a first drive device for positioning the moving body is decreased. CONSTITUTION:A first feed screw 3 is coupled to a moving body 5 through a nut, and a second feed screw 4 is coupled to a piston 6 of a hydraulic cylinder 6, secured to the moving body 5, through a nut. The second feed screw 4 applies a target set pressure Pmc, responding to a position deviation E, on the cylinder 6 through an external compensator 8, and burdens the inertia reaction force of the moving body 5. Acceleration of the moving body 5 is made equal to the conversion value in a moving direction of angular acceleration of a feed motor 2. Namely, the inertia reaction force of the moving body 5 exerted on the first feed screw 3 is reduced to zero, resilient deformation is decreased, and an apparent rigidity value is set to infinity. Since stability of a control system is increased, this constitution enables improvement of response through increase of a gain, and enables improvement of positioning precision during high response operation.

摘要： PURPOSE:To perform Y-axis machining with relative ease and low-cost structure by providing a turret with a rotary tool unit in a swivel free manner to allow an end mill to perform machining while putting a work and the rotary tool unit into synchronous rotation. CONSTITUTION:Quick positioning is performed at the start of machining by the swivel and crosswise movement of a turret 4, because the swivel of the turret 4 is driven by a powerful index motor. After finishing positioning, a work 3 and a tool holder 7 synchronously rotate and on the other hand a tool 8 starts rotating to perform Y-axis machining, when the turret 4 slides crosswise to keep a distance between the work 3 and the tool 8 constant and to perform cutting corresponding to an allowable machining amount. In this case, as cutting reaction applied to the servo motor which drives the tool holder 7 is not so much as rotating force necessary for the swivel of the turret 4, the servo motor is sufficient with a relatively small type.

摘要： PURPOSE:To enable a definite depth of cut to be always maintained even if the diameter of a rotary knife is varied because of wear by calculating the actual depth of cut by said knife, comparing the result with the preset depth of cut and making adjustment so that these two agree with each other. CONSTITUTION:In adjusting the depth of cut by rotary knives for grinders, side milling cutters, etc., against a workpiece, the axial center (0) of a rotary knife 1 is made the origin of coordinates, and the coordinates (X, Y) of the contact point A between the knife 1 and the workpiece 3 are found. Since the diameter of the knife 1 becomes (X +Y ) from these coordinates, the actual depth of cut S can be calculated by S=(X -Y ) -Y. By comparing this value with the preset referential depth of cut, the knife 1 and the workpiece 3 are relatively moved in the Y direction so that these two values agree with each other. By this method, a constantly definite depth of cut is maintained even if the diameter of the knife 1 is varied because of wear.
摘要翻译：目的：为了确保切割深度始终保持，即使旋转刀的直径由于通过计算所述刀的实际切割深度而导致的磨损而变化，将结果与预设的切割深度和调整深度进行比较这两个人相互认同。规定：在将研磨机，侧铣刀等的旋转刀的切削深度调整到工件上时，将旋转刀1的轴心（0）设为坐标原点，坐标（X，Y ）在刀1和工件3之间的接触点A. 由于刀具1的直径从这些坐标变为（X 2 + Y 2）1/2，所以实际的切削深度S可以通过S =（X 2 -Y 2））1/2。通过比较该值与预设的参考深度切割，刀1和工件3在Y方向上相对移动，使得这两个值彼此一致。通过这种方法，即使刀1的直径由于磨损而变化，也保持不断确定的切割深度。

摘要： PURPOSE:To lessen backlash errors or the like by controlling an oil amount to a hydraulic cylinder of a second feeder with a difference between a command acceleration signal to a first feeder for locating a mover and an acceleration signal of the mover. CONSTITUTION:A position-speed signal 20 from a controller 10 is sent to a motor 4 through a motor control unit 9 to locate a mover 1 by a ball screw 3 and a nut 2, while a position-speed detecting signal 21 is fed back from the motor 4. Then, pistons 14a, 14b are driven through a pulley 17, timing belt 19, pulley 18, ball screw 16, nut 15 and bracket 26 to give a drive force to the mover 1 by hydraulic cylinders 5a, 5b. Also, a pressure control unit 6 sends to the hydraulic cylinders 5a, 5b a flow corresponding to the deviation between a command acceleration signal 24 from the controller 10 and an acceleration signal from an acceleration detector 25 of mover 1 according to both signals. Thus, wind-up and backlash errors can be reduced and a compact hydraulic cylinder can be provided.

摘要： PURPOSE:To secure the working precision of a machine tool by preventing the thermal deformation of a hollow constitution member due to the difference of the temperature response speed in the same member for the change of the outside air temperature by charging liquid into the hollow part of the hollow constitution member. CONSTITUTION:When a temperature difference is generated between the parts of a constitution member 21, natural convection is generated in the liquid 22 in a hollow part by the change of liquid density. Since the heat transfer from the high-temperature part of the constitution member 21 to the low-temperature part through the liquid 22 in the hollow part by the natural convection in this case, the generated temperature difference is offset, and the max. temperature difference generated between the parts of the constitution member 21 is kept at a small value. Further, by charging liquid into the hollow part of the constitution member 21, the heat capacity of the liquid 22 is added, and the same effect to the increase of the body thickness of the constitution member 21 can be obtained, and the following of the temperature of the constitution member 21 to the change of the outside air temperature can be suppressed, and also the temperature difference generated between the parts of the constitution member 21 is reduced, and the thermal deformation can be suppressed, and a machine tool having a high precision can be obtained.
摘要翻译：目的：为了通过防止由于将液体注入中空部分中的外部空气温度的变化而导致的同一部件中的温度响应速度的差异，防止中空构造构件的热变形，从而确保机床的工作精度中空构造构件。构成：当在构成构件21的部分之间产生温度差时，通过液体密度的变化在中空部分中的液体22中产生自然对流。在这种情况下，由于通过自然对流将构成构件21的高温部分从中空部分的液体22传递到低温部分，所以产生的温度差被偏移，在构成构件21的各部分之间产生的温差保持在较小的值。此外，通过将液体加入到构成构件21的中空部分中，添加液体22的热容量，并且可以获得与构成构件21的体厚增加相同的效果，并且可以抑制构成构件21的温度与外部空气温度的变化，并且构成构件21的各部分之间产生的温差也减小，并且可以抑制热变形，并且具有高的机械可以获得精度。
