JOINT AMOUNT CONTROL DEVICE, JOINT AMOUNT CONTROL METHOD, JOINT AMOUNT CONTROL PROGRAM, AND LASER PROCESSING DEVICE

A processing program analysis unit (13) analyzes a processing program, and extracts a first and a second code which are included in the processing program and which indicate the joint-configuring pair of a first endpoint on the laser cutting start side of a cutting path and a second endpoint on the laser cutting end side of the cutting path. A joint information adding unit (14) adds, to the processing program, joint information indicating the position of the first code and/or the second code. A joint correction amount generation unit (15) generates a joint correction amount configured for the joint the joint amount of which is to be increased or decreased. A transmission unit (the central control unit (11)) transmits to an NC device (21) the processing program to which the joint information has been added, and the joint correction amount with which information has been associated that indicates the joint the joint amount of which is to be increased or decreased. 加工程序解析部(13)对加工程序进行解析，提取加工程序所包含的、表示构成接头的激光切断开始侧的
