磁力吸着された被加工材のすべり抵抗性に及ぼす継鉄間寸法の影響

抄録

The electro magnetic clamping device has been widely used for surface grounding or other machining processes. On the other hand, the permanent magnetic clamping devise is expected to apply for the multi-axis machining for small mechanical parts with complicated form. In this study, we measured the magnetic attractive forces and tangential sliding forces for the low carbon steel specimens using the experimental permanent clamping devices which have different separator width 3, 5 and 6 mm. The attractive force increased to 169.3 N with increase in projection areas. However, the tangential force did not depend on the projection areas indicsted.
