摘要： A powder compaction mold includes a die and upper and lower punches configured to fit into the die and is configured to compress a powder between the upper and lower punches to manufacture a powder compact. Of the members forming the powder compaction mold, at least one of two members in sliding contact with each other has therein a vent passage through which gas is vented from a filling space for the powder surrounded by the die and the lower punch to an outside of the powder compaction mold. The vent passage has a gas intake port that is open to a clearance section formed between the two members and connecting to the filling space.

摘要： A throwaway insert includes a base and a cutting edge member. The cutting edge member includes: a rake face; a flank face extending to cross the rake face; a first connecting face connecting the flank face to a side surface of the base and extending to cross the rake face; and a first ridgeline formed by the rake face and the flank face and serving as a cutting edge. When viewed in a plan view from the upper surface of the base, the flank face and the first connecting face are located external to the base. A second ridgeline formed by the rake face and the first connecting face crosses the first ridgeline at an obtuse angle.
