Abstract
A machining path generation device which generates a cutting path upon rough cutting a workpiece by a turning process, and a numerical control device equipped therewith, are provided to shorten the path during rough cutting, and thus reliably shorten the cycle time. The device includes a storage unit which stores information of a cutting start point and a cutting end point of rough cutting; a finishing allowance permitted range setting unit which sets a finishing allowance permitted range for a finishing step; and a cutting path generation unit which generates a cutting path connecting the cutting start point and the cutting end point in a cross-sectional view in a direction along a rotation axis line of the workpiece, the cutting path arranged within the finishing allowance permitted range, and shorter than a path following along a shape line of a product form.
