Title:
MANUFACTURING METHOD OF GROOVED MEMBER
Document Type and Number:
Japanese Patent JP2016094974
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of a grooved member for forming a groove at a groove forming surface at a soft processed member in which a workability of the groove can be further improved.SOLUTION: This invention relates to a manufacturing method of a grooved member 1 by forming a groove 3 at a groove forming surface 21 at a soft processed member 2. The groove 3 has one side edge 31, the other side edge 32 and a connecting part 33 between one side edge 31 and the other side edge 32 as seen in a vertical sectional view along a width direction WD. A knife N capable of cutting substantially without forming any cut debris is applied, the knife N is inserted into the groove forming surface 21, the knife N is moved in a longitudinal direction where the groove 3 extends. At first, one side edge 31 is formed and subsequently the other side edge 32 is formed, a separation portion 34 defined by one side edge 31, the other side edge 32 and the connecting part 33 is removed from the processed member 2, resulting in that a grooved member 1 is attained.SELECTED DRAWING: Figure 3
