POSITION DETERMINATION DEVICE OF CASTORIES LINE, CUTTING SYSTEM, COMPUTER PROGRAM FOR DETERMINATION OF POSITION OF CASTORIES LINE, METHOD FOR DETERMINATION OF POSITION OF CASTORIES LINE

Japanese Patent JP2018099761

A

PROBLEM TO BE SOLVED: To locate a castories line at an optimum position.SOLUTION: A candidate point selection part 104 of a position determination device 100 selects plural points on plural contour lines 80 of an object 70 as a candidate point. A search point selection part 105 selects a search point which becomes a basis for searching for a point which becomes an end point of a castories line from the candidate points. A base line setting part 106 sets a line which combines a reference point and the search point as a base line. A candidate line setting part 108 sets a line which respectively combines points of plural candidate points excluding the search point and the search point as a candidate line. A selection part 110 so makes a candidate line located in only a non-effective region 56 as to be a selection candidate line. An angle calculation part 112 calculates an angle formed by the base line and the selection candidate line. A first castories line setting part 114 sets a line which combines a candidate point on a selection candidate line which has a calculated smallest angle and the search point as a first castories line. A second castories line setting part 120 sets a second castories line which is different from the first castories line.SELECTED DRAWING: Figure 4
