Laminated shaping path generation device, laminated shaping path generation method, and machine learning device

A laminate shaping path generation device (200) is provided with: a shaping path generation unit (202) that generates a shaping path on the basis of layer definition information that defines a division of a laminate shaped object into layers that serve as shaping units, and a shaping path surface that is a surface that restricts the position of a shaping path; dividing the laminated shaped object into layers so that the shaping height of a bead for shaping the layers does not exceed an upper limit value, and generating a shaping path which is a path for shaping the divided layers; and a shaping path correction unit (205) that corrects the shaping path to a shaping path in which a plurality of layers are locally shaped together within a range in which the shaping height is within the upper limit value and the lower limit value. 层叠造形路径生成装置(200)具有：造形路径生成部(202)，其根据对将层叠造形物向成为造形单位的层的分割进行定义的层定义信息、和对造形路径的位置进行限制的面即造形路径面，以造形出层的焊道的造形高度不超过上限值的方式将层叠造形物分割为层，生成造形出分割后的层的路径即造形路径；以及造形路径修正部(205)，其将造形路径修正为在造形高度处于上限值和下限值的范围内局部地一并
