摘要： A groove (Da) extending in a Y-axis direction of a workpiece (D) is finish machined with an offset tool (T) that has a cross-section with a shape (L3) offset in a reducing direction by only a predetermined offset amount relative to a finished shape (L1) of the groove (Da) and that rotates around an axis of rotation parallel to a Z axis. Each time an incising step in which the offset tool (T) is relatively moved within the X-Z plane only by a predetermined distance on the circumference of an imaginary circle (C) having an initial position as its center and the offset amount (o) as its radius is carried out, a cutting step in which the entire length of the groove (Da) is cut while relatively moving the offset tool (T) in the Y-axis direction is carried out repeatedly. This enables the load imposed on the offset tool (T) to be suppressed compared with the case of a forming tool, which cuts a wide region of the groove (Da) of the workpiece (D) all at once, thus providing a method of machining a workpiece with an offset tool (T), the method allowing the durability of the offset tool (T) to be enhanced and the finishing precision of a machined face to be increased.
摘要翻译：在工件（D）的Y轴方向上延伸的凹槽（Da）用带有形状（L3）的横截面在减小方向上仅具有预定偏移量的偏移工具（T）精加工相对于槽（Da）的成品形状（L1）的量并且围绕平行于Z轴的旋转轴线旋转。每次在偏移刀具（T）在XZ平面内相对移动预定距离的切割步骤，该预定距离以具有初始位置为中心的假想圆（C）的圆周为止，偏移量（o）为执行其半径，重复执行在沿着Y轴方向相对移动偏移工具（T）的同时切割槽（Da）的整个长度的切割步骤。与成形工具的情况相比，能够抑制施加在偏移工具（T）上的负荷，该成形工具一次切割工件（D）的槽（Da）的宽区域，因此提供了一种方法使用偏移刀具（T）加工工件，可以提高允许偏移刀具（T）的耐用性的方法，并提高加工面的精加工精度。

摘要： During continuous casting of metals, a non-moving, vibrating magnetic field is applied to a molten metal in a casting mold to impose only vibration on the molten metal. This continuous casting method can produce a cast slab much less susceptible to flux entrainment, capture of bubbles and non-metal inclusions near the surface of the molten metal, and surface segregation. The magnetic field is preferably produced by arranging electromagnets in an opposing relation on both sides of the mold to lie side by side in the direction of longitudinal width of the mold, and supplying a single-phase AC current to each coil. The single-phase AC current preferably has frequency of 0.10 to 60 Hz. A static magnetic field can be applied intermittently in the direction of thickness of a cast slab. This technique can produce a cast slab substantially free from the flux entrainment and the surface segregation. Preferably, the static magnetic field is intermittently applied under setting of an on-time t1=0.10 to 30 seconds and an off-time t0=0.10 to 30 seconds. Also, the static magnetic field is preferably applied to the surface of the molten metal.
