  I .刀軌規劃
  I. tool path planning
  1.??诤穸龋涸跈C床能承受的很大載荷下,應選擇較大的刀具、較大的進給量和較快快的進給量。在同一把刀的情況下,進給與進給量成反比。正常情況下,機床的負荷不成問題,刀具選擇的原則主要是根據產品的二維角度和三維圓弧是否太小。選擇刀后,確定刀的長度。原理是刀具長度大于加工深度。對于大型工件,應考慮卡盤是否干涉。
  1. Die thickness: under the large load that the machine tool can bear, large cutter, large feed and fast feed should be selected. In the case of the same tool, the feed is inversely proportional to the feed. Under normal circumstances, the load of the machine tool is not a problem. The principle of tool selection is mainly based on whether the two-dimensional angle and three-dimensional arc of the product are too small. After selecting a knife, determine the length of the knife. The principle is that the tool length is greater than the machining depth. For large workpieces, the interference of chuck shall be considered.
  2.模具光刀:光刀的目的是滿足工件表面光潔度的加工要求,并留有適當的余量。同樣地,光滑的刀應該盡可能大,并且時間應該盡可能快,因為精細的刀需要更長的時間,并且應該使用合適的進給和進給。在相同的進給下,橫向進給越大,速度越快。曲面的進給量與加工后的光潔度有關。進給尺寸與曲面的表面形狀有關。在不損壞表面的情況下,保持小余量、大刀具、快轉速和適當進給。
  2. Mold smooth knife: the purpose of the smooth knife is to meet the processing requirements of the workpiece surface finish, and to leave appropriate margin. Similarly, smooth knives should be as large as possible, and the time should be as fast as possible, because fine knives take longer, and appropriate feeds and feeds should be used. In the same feed, the greater the cross feed, the faster the speed. The feed rate of curved surface is related to the finish after machining. The feed size is related to the surface shape of the surface. Keep small allowance, large tool, fast speed and proper feed without damaging the surface.
  二、合模方法:
  2、 Mold closing method:
  1.虎鉗夾緊:夾緊高度不應小于10毫米,加工工件時必須規定夾緊高度和加工高度。加工高度應比虎鉗平面高5毫米左右,以保證牢固性而不損壞虎鉗。這種夾緊屬于一般夾緊。夾緊高度也與工件的尺寸有關。工件越大,夾緊高度越高。
  1. Vise clamping: the clamping height shall not be less than 10 mm, and the clamping height and processing height must be specified when processing workpieces. The machining height should be about 5mm higher than the plane of the vise to ensure the firmness without damaging the vise. This kind of clamping belongs to general clamping. The clamping height is also related to the size of the workpiece. The larger the workpiece, the higher the clamping height.
  2.夾板夾緊:夾板在工作臺上用代碼編碼,工件用螺釘鎖在夾板上。這種夾緊方式適用于夾緊高度不足、加工力大的工件,一般適用于效果好的大中型工件。
  2. Splint clamping: the splint is coded on the workbench, and the workpiece is locked on the splint with screws. This kind of clamping method is suitable for the workpieces with insufficient clamping height and large machining force, and generally suitable for the large and medium workpieces with good effect.
  3、碼鐵裝夾:在工件較大、裝夾高度不夠,又不準在底部鎖螺絲時,則用碼鐵裝夾。此種裝夾需二次裝夾,先碼好四角,加工好其它部分,然后再碼四邊,加工四角。二次裝夾時,不要讓工件松動,先碼再松。也可以先碼兩邊,加工另兩邊。
  3. Code iron clamping: when the workpiece is large, the clamping height is not enough, and it is not allowed to lock the screw at the bottom, the code iron clamping shall be used. This kind of clamping requires secondary clamping, first code four corners, process other parts, then code four corners, process four corners. During the second clamping, do not let the workpiece loose, first code and then loosen. You can also code two sides first and process the other two sides.
  4、刀具的裝夾:直徑10mm以上,裝夾長度不低于30mm;直徑10mm以下,裝夾長度不低于20mm。刀具的裝夾要牢固,嚴防撞刀與直接插入工件。
  4. Clamping of cutter: the diameter is more than 10 mm, and the clamping length is not less than 30 mm; the diameter is less than 10 mm, and the clamping length is not less than 20 mm. The clamping of the cutter shall be firm, and it shall be strictly prevented from hitting the cutter and directly inserting the workpiece.
  三、加工工藝的選擇:
  3、 Selection of processing technology:
  1、曲面挖槽:范圍的選擇與面的選擇
  1. Surface trenching: range selection and face selection
  刀路加工區域:以所選范圍內所選面為終止面,從高點到低點刀具能下得去的所有地方為原則。所選面盡量是全體面,邊界則只能是所要加工的區域,無面延伸小于半個刀徑的距離,因為其它面留有足夠余量所以自動保護;盡量延伸低限度,因為低限處有一個R鑼不到。
  Tool path processing area: the selected surface within the selected range is the termination surface, and all places that the tool can go down from the high point to the low point are the principle. The selected face shall be full face as far as possible, and the boundary shall only be the area to be processed. No face extends less than half of the cutter diameter, because other faces have enough margin, so it is automatically protected; extend as far as possible, because there is less than one R gong at the lower limit.、
  刀的選擇:如刀具不能螺旋或斜線進刀時或加工不到的區域進不了刀的區域封起,留待二次開粗。
  Selection of cutter: if the cutter can't enter the helix or oblique line, or the machining area can't enter the cutter, the area shall be sealed and left for the second opening.
  光刀之前,一定要把未開粗的區域全部開粗,特別是小角,其中包括二維角,三維角及封起來的區域,不然則會斷刀。二次開粗:一般用三維挖槽選范圍,平底刀,能用平面挖槽與外形刀路的則用。在不傷及其它面的情況下刀具到所選高,當挖槽形狀為條形,不能螺旋下刀則用斜線進刀,一般打開過濾,特別是曲面開粗,進刀平面不可低,以免撞刀,安全高度不可低。
  Before the smooth knife, it is necessary to make all the areas that have not been cut thick, especially small angles, including two-dimensional angle, three-dimensional angle and sealed area, or the knife will be broken. Secondary roughening: it is generally used to select the range of three-dimensional trenching, flat bottomed cutter, and the one that can use plane trenching and profile cutter path. Without damaging other surfaces, the center of the tool is to the selected height. When the groove shape is strip shape, and it is impossible to screw down the tool, the oblique line is used to feed the tool. Generally, the filter is opened, especially when the curved surface is rough, and the feed plane cannot be low, so as to avoid hitting the tool, and the safety height cannot be low.
  退刀:一般不用相對退刀,用絕對退刀,當沒有島嶼則用相對退刀。
  Back off: generally, relative back off is not used. Absolute back off is used. If there is no island, relative back off is used.
  2、平面挖槽:銑各種平面,凹平槽,當銑部分開放式平面時,則需定邊界,原則能進刀(大于一個刀徑),開放處偏外大于半個刀徑,封閉外圍。
  2. Plane slotting: milling all kinds of plane, concave and flat groove. When milling part of the open plane, it is necessary to determine the boundary. In principle, it can feed (more than one knife diameter), the opening part is more than half of the knife diameter, and the periphery is closed.
  3、外形:當所選平面適合外形分層,則用外形分層提刀(平面外形),提刀點與下刀點為一點時,不須提刀Z平面一般提刀,盡量不用相對高度;補正方向一般右補正(順刀)。
  3. Profile: when the selected plane is suitable for profile layering, the profile layering tool lifting (plane profile) is used. When the tool lifting point and the lower tool point are one point, the z-plane tool lifting is not necessary, and the relative height is not needed as much as possible; the direction of correction is generally right correction (along the tool).
  4、機械補正的刀路設置:補正號為21,改電腦補正機械補正,進刀為垂直進刀,刀過不了的地方則改大R不留余量。
  4. Setting of tool path for mechanical correction: the correction number is 21, and the computer correction is changed to mechanical correction. The feed is vertical feed, and the area where the knife cannot pass is increased by R without margin.
  5、等高外形:適合于走封閉式的面,走開放式的面若是四圈則要封項面,若是四圈內或非四圈則要選范圍與高度(一定弧形進刀開粗),用于開粗的情況:任一平面內的加工距離小于一個刀徑,若大于一個刀徑則要用更大的刀或兩次等高外形。
  5. Contour of equal height: it is suitable for the closed face. If the open face is four circles, it is required to seal the item face. If it is within four circles or not, it is required to select the range and height (certain arc feed is required to be rough). It is used for the case of rough cutting: the processing distance in any plane is less than one cutter diameter, if it is larger than one cutter diameter, it is required to use a larger cutter or two contour of equal height.
  6、曲面流線:具有較好的均勻性與干脆性,適合光刀很多時候可取代等高外形。
  6. Curved streamline: with good uniformity and dry brittleness, it is suitable for smooth knife to replace contour in many cases.
  7、放射刀路:適合中間有大孔的情況(少用)。注意事項:彈刀,刀不鋒利,刀過長,工件過深時要環繞走不可上下走;工件中的利角兩邊的面要分兩個刀路,不可越過去,光刀時的邊緣延長(用弧線進退刀)。
  7. Radial knife path: suitable for the case with large hole in the middle (less use). Note: the spring knife is not sharp, and the knife is too long. When the workpiece is too deep, it should not go up or down around; the surfaces on both sides of the sharp angle in the workpiece should be divided into two knife paths, which should not go over, and the edge of the smooth knife should be extended (use arc to advance or retreat the knife).
