Abstract
(EN)
The present invention generates a tool route with high machining efficiency regardless of the shape of machining area. A tool route generating device for generating a tool route for applying contour machining to a work piece with rotary cutting tools comprises: a data input unit (101) for inputting data required for the generation of tool route; a machining condition setting unit (102) for setting a machining condition; and a tool route generating unit (106) for generating a tool route on the basis of the set machining condition, wherein the machining condition setting unit (102) includes: a machining cross-sectional area computing unit (103) for computing machining cross-sectional areas divided for each height when machining with the rotary cutting tools the areas to be machined along the tool route; a radial depth of cut computing unit (104) for setting a radial depth of cut such that the radial depth of cut in the computed machining cross-sectional areas becomes integral divisions of the radial maximum cutting width in the machining cross-sectional area; and an axial depth of cut computing unit (105) for changing a value of the axial depth of cut depending on the set radial depth of cut.
