利用图解法绘制金属板件的表面展开图

Surface Development of Metal Sheet

在工业生产中,经常会有许多金属薄板制件.这些金属板制件在制作过程中必须先在金属板上画出展开图,然后划线、下料、工序加工成型,最后焊接或铆接而成.利用图解法可以较为方便地制作这些制件的表面展开图,从而实现金属板件的精确下料.

In the production of industry, there are many metal sheet productiom. During the process, tint, we need to draw the sruface development, and process, finally, joint. By usine the picture, we can make use of the surface development in order to the accuracy.
