A262 •長度單位 Unit of Length (mm) CUTTING HCM 切削技術資料 - 如何正確選擇刀具 HCMTECHNICAL INFO -HOWTOCHOOSE A CUTTER 切削的刃數與切削力變動的關係 Relation between the number of simultaneously engaged cutting edges and cutting force 形式Form 同時參與切削刃數為 0 或者 1 時 0 or 1 edge in contact at same time. 常態為 1 片切削時 Only 1 edge in contact at any time. 1 片或 2 片切削時 1 or 2 edges in contact. 2 片切削時 2 edge in contact at any time. 2~3 片切削時 2 to 3 edge in contact. 說明Description 通常切削寬度如 D 的狀態，銑刀直徑在 70%~80% 較為適當，但由於受機台和工件的剛性、機台馬力的影響，無法一概而論 Normally, cutting width is considered to be appropriate with 70 to 80% of the cutter diameter engaged as shown in example D. However, this may not apply due to the actual rigidity of the machine or work piece, and machine horsepower. 建議使用刀具尺寸規格Suggest used the cutter spec. 規格 Spec.

Processing pi thin pieces. 2. Processing clamping rigid workpiece. 3. Large cutting. 適用 : 1. 加工粗胚 2. 中大切削工件 General: 1. Processing rough embryos. 2. Large cutting parts. 適用 : 1. 加工深腔體工件 2. 中切深 General: 1. Processing of deep cavity workpiece. 2. In the depth of cut. 適用 : 1. 加工大量粗切削 2. 小切深、大進給 General: 1. Processing a large number of rough cutting. 2. Small depth of cut, large feed. 範例Example: 0.2 0.05 100 100-0.2 2.23 說明Description 外周切削刃角 ( 主偏角的餘角 ) 越大，則切屑厚度越大，切削阻力增加，刃口強度降低；反之則切屑厚度越薄，切削阻力減少，加工餘量受限。 一般加工選用切削力，切屑厚度適中的 45°角。 The larger the chip angle is, the greater the chip thickness is, and the cutting resistance is increased. The cutting edge strength is reduced. General processing selection of cutting force, chip thickness of moderate 45 ° angle. 選擇刀片座種類 Choice the insert seat type 90° 75° 45° 12° Dc=100 f =0.05 Ap=0.2 3 4
