description A method and a system for determining a heating point and a heating line in steel plate bending place a virtual wooden pattern on a virtual steel plate; roll the wooden pattern or steel plate along a frame line from a reference position to contact the wooden pattern and steel plate at two points A, B on the steel plate and C, D on the wooden pattern; roll the wooden pattern or steel plate in the reverse direction for return to the reference position; obtain straight lines U, V connecting the contact points A, B and C, D, respectively; determine a heating point relative to a reference point based on an intersection point of the straight lines U, V; repeat the same steps while contacting the contact points A, C on a reference point side to use their contact point as a new reference point, to determine respective heating points along a specific line up to the end of the steel plate; draw straight lines from a certain heating point on a certain line to heating points on other lines based on the determined heating points; examine the degree of parallelism between each straight line and a roller line; if the degree is within a predetermined range, group the relevant heating points as the same group; and connect the heating points of the same group by a straight line or a curve to determine a heating line.
