Abstract

PURPOSE:To improve the accuracy and speed of working by enabling working of reference planes by using a cutter having a large diameter and forming the relief parts of the sharp edges of a prism. CONSTITUTION:The prism 41 is pressed, positioned and fixed to the 1st reference planes 23, 25 and 2nd reference plane 33 intersecting orthogonally with each other. The 1st reference plane consists of the right side 1st reference plane 23 and the left side 1st reference plane 25. The 2nd reference plane 33 exists forward in a recessed part 27 between these planes. The reference planes 23, 25, 33 and the relief parts 35 are precisely cut and worked by advancing a cutter for cutting while utilizing the space part between the recessed part 27 side of the 1st reference planes 23, 25 and the 2nd reference plane 33 and the recessed part 27.

At least the center of the surface of the prism 41 is preferably brought into contact with the second reference surface 33 provided in front of the recess 27. Also, the right and left first reference planes 2
In front of the end portions 23a and 25a of the concave portions 3 and 25 on the recessed portion 27 side, there is a space portion where the second reference surface 33 does not exist. The second reference plane 33 and the first reference planes 23 and 25 do not intersect,
The first reference surfaces 23 and 25 extend below the height of the second reference surface 33. Therefore, between the first reference surfaces 23 and 25 and the second reference surface 33, the nipping portion 35 of the sharp edge 41a of the prism 41 (see also FIG. 5B) is formed.

As shown in FIG. 5, the block 1 before processing
In 1 ', even if it is attempted to cut the first surface 21 and the second surface 31 vertically, there is an R based on the diameter of the cutting cutter between them. Therefore, if a prism is to be brought into contact with the first surface 21 and the second surface 31 without forming a nig portion, the sharp edge of the prism interferes with the R portion, resulting in poor positioning accuracy. Therefore, in the present invention, it is prevented that the first reference planes 23 and 25 and the second reference plane 33 directly intersect each other and R is inevitably generated.
(Or 25) and 33 so that they do not intersect directly
5 is formed.
