图22中，底板430上表面为平面，保护膜片材408为片状，平铺在底板上，底板上有多个定位块432，能定位固定片材。美甲机的侧部能有一开口，底板和片材能从开口放入美甲机中。美甲机中有底板承托机构，能固定底板。放入后的底板位于雕刻执行模块下方。片材的尺寸能输入到雕刻模块中。片材为单层/多层薄片，能是弹性材料，如橡胶、塑料，能是非弹性材料，如纸、金属箔。优选面材层/基材层复合结构，面材层下表面涂胶。雕刻模块能根据手指二维图形生成防护膜的轮廓，并在片材上规划出多个防护膜的排版。雕刻执行模块能在底板上方三维运动，在片材上裁切出防护膜。优选采用激光雕刻方式裁切防护膜，底板能防护激光。裁切完成后，从美甲机中取出底板，从片材上取下防护膜。能采用雕刻执行模块的激光器/雕刻刀不移动，而用伺服机构带动底板移动以裁切防护膜的方案。
防护膜能包括2个/多个分片。图23中，防护膜包括一个后片420，一个右片421，一个左片422。因为指甲两侧和后部的手指表面形态是三维曲面，为了能使防护膜更加贴合指甲周围的手指，能把防护膜分划为多个分片。使用时，把各分片分别贴在指甲周围对应的位置上，组合成完整的防护膜。
图24是各分片组合后的状态，各分片间有重叠部分，互相叠压。使用时，首先把右片/左片贴在指甲两侧，按压右片/左片，使两片紧密贴合在指甲两侧的手指皮肤上。然后把后片贴在指甲后部，叠压在右片和左片上。多个分片的结构能使防护膜更贴合手指曲面。测量模块测量出指甲/手指的三维模型后，能根据三维模型的曲面形态确定防护膜的立体曲面形态。能取保护膜的立体曲面形态为手指末节三维模型的曲面形态。测量模块能根据保护膜的三维曲面形态或二维平面形状把保护膜划分成多个分片。划分的方法包括但不限于沿曲面波峰划分、沿波谷划分、沿峰顶谷底连线划分。能沿曲面的某种特征值分布划分，如沿曲面梯度数值/方向变化剧烈的网格间边界连线划分。测量模块能计算防护膜曲面各网格/点的梯度。设定一梯度数值或方向的变化阙值t，当曲面相邻网格梯度变化数值大于t时，把梯度变化极大的相邻网格/点之间的连线定为一条分界线，沿该分界线把保护膜分成两片。能确定多条分界线，多条分界线能把保护膜划分为多片。分片划分完成后，各分片沿划分分界线向外延伸0～ 20mm，以保证各分片贴合后能重叠。分片与指甲的边界不延伸。能沿指甲右侧与后部分界处、左侧与后部分界处把防护膜分为三片。能沿指甲右侧与后部分界处、左侧与后部分界处、右侧与前部分界处、左侧与前部分界处把防护膜分为四片。测量模块把每个分片的三维曲面拓扑展开成二维平面形状并传递给雕刻模块，雕刻模块能在印膜或防护膜片材上裁切出保护膜各分片。
图25中，印膜执行模块73能沿滑轨742滑动。喷绘时、雕刻时，印膜执行模块位于执行装置12内部。当防护膜裁切完或更换印膜时，印膜执行模块能从执行装置内部滑出到预备位置750，暴露在外部。此时能更换印膜，或把防护膜从印膜上取下。
