摘要： PURPOSE:To designate all processes on one picture by giving a number onto a solid figure or a development of a product, designating a stop line and a bending line by said number at every process on a bending process input picture and generating a schedule of all bending processes. CONSTITUTION:A product shape input and a working information input are executed. Product shape data shows that shape data of a solid figure has been inputted, and working information is data for designating a shape of a die for executing a simulation afterward. Subsequently, a number is given to a segment corresponding to a bending line and a stop line. Next, a schedule of all processes is generated by inputting the stop line, the bending line and die number of a punch and a die at every process on another bending order data input picture. In case when it is desired to confirm the designated bending order, it can be executed by displaying all the processes on one picture confirming an error and correcting it, and thereafter, pushing a button of 'end'. The input contents are inputted to a storage device and utilized for the subsequent processing. In such a way, the bending order can be inputted in a lump on one picture, and the bending input can be executed easily by simple knowledge.
