1.手板工藝路線制定可先按照工件需要分兩次加工。先加工手板的外觀內(nèi)壁，銑好基準(zhǔn)，再翻轉(zhuǎn)180度裝夾，加工外表面及按鍵屏幕位置。若先加工外表面，再加工內(nèi)壁，則難以定位裝夾進(jìn)行二次加工。

1. The development of the prototype process route can be divided into two processing steps according to the needs of the workpiece. First, process the appearance and inner wall of the hand board, mill the benchmark, then flip it 180 degrees to clamp it, and process the outer surface and button screen position. If the outer surface is processed first and then the inner wall is processed, it will be difficult to locate and clamp for secondary processing.

2.如果手板的壁厚只有1.5mm，加工外表面時(shí)易出現(xiàn)變形、破碎的現(xiàn)象。如有在已加工好的型腔中加入填充物做出支撐。這樣可避免加工出通孔部位，再填充石膏，否則很難分離成品和填充物。

If the wall thickness of the hand board is only 1.5mm, it is prone to deformation and breakage when processing the outer surface. If any filling material is added to the processed cavity for support. This can avoid processing the through-hole area and then filling it with gypsum, otherwise it is difficult to separate the finished product and the filling material.

3.要先修復(fù)修剪的曲面，掩蓋住表面通孔位置，進(jìn)行正面加工，然后再進(jìn)行挖槽完成通孔加工，以免加工到通孔部位加工時(shí)刀路起伏不順暢，切削力不均勻等現(xiàn)象。

3. The trimmed surface should be repaired first, covering the position of the surface through hole, and then machining on the front side. Then, groove excavation should be carried out to complete the through hole machining, in order to avoid uneven tool path and cutting force when machining to the through hole position.

4.手板上的各種零件應(yīng)有足夠的強(qiáng)度及剛度，防止使用過程中損壞和變形，手板上的各種零件應(yīng)有足夠的強(qiáng)度及剛度，防止使用過程中損壞和變形，緊固零件要有防松動(dòng)措施，避免意外傷害操作者。不允許在加工過程中發(fā)生廢料或工件飛彈現(xiàn)象，影響操作者的注意力，甚擊傷操作者。另外要避免沖裁件毛刺割傷人手。

4. The various parts on the hand board should have sufficient strength and stiffness to prevent damage and deformation during use. The various parts on the hand board should have sufficient strength and stiffness to prevent damage and deformation during use. The fastening parts should have anti loosening measures to avoid accidental injury to the operator. It is not allowed to have waste or workpiece missiles during the processing, which may affect the operator's attention or even injure the operator. Additionally, it is important to avoid cutting hands with burrs on the punched parts.
