(No.1) 0° (3) Measure the blade width of the slot mill body at position No.1. No.7 No.4 (between point A and B in the figure) High Feed A (4) Move the length measuring equipment to the insert corner part Multi- No.8 and measure the step (Y1) between the point A and the insert Function No.1. Slot Mill (5) Using the same procedure, measure (Y2) dimension based on No.3 point B. Ball-nose No.1 No.2 Edge Width = Blade Width + Y1 + Y2 Radius (6) Place the point A of the slot mill body near the position No.1 to Others B "0 (zero)" of the length measuring equipment. "No.1-No8" in the gure is for explanation. There are no indications on the slot mill body. (7) Adjust the edge position of the inserts in odd numbered positions (No. 3, 5, 7) to "0 (zero)" with the length measuring equipment. Y1 (8) Adjust the edge position of the inserts in even numbered positions (No. 2, 4, 6, 8) to the required edge width. Body Blade width Edge Width For steps (7) and (8), see "In the case of changing the slot width (edge width)" on next page. Y2 M162
