The program creates the bend using the bend radius defined in the sheet metal style.

程式使用板金型式中定义的折弯半径建立折弯。

The sheet of metal is moved in a helical trajectory such that the second bend comes into proximity above the first bend.

该金属 板沿螺旋形轨迹移动使得该第二弯曲进入该第一弯曲的上方邻近处。

The upper and lower longitudinal edges of the metal sheet are bent to produce a first 'l' bend and a second 'chair' bend, respectively.

弯曲该金属板的上、下纵向边缘以分别形成第一“L”形弯曲和第二“椅”形弯曲。

Scoring Part: adopt 5 points scoring, scoring distance in-phase adjust, blazonry and easy to bend the carton sheet.

压痕部：采用五点压线，压痕间隙同步调整线型美观，不爆线，易于折弯。
