PURPOSE:To prevent a tool from breaking, by measuring respectively a matrix division, divisionally formed on the basis of an input data, while storing in memory the ruggedness distribution of a machining surface and distributively displaying its height being classified by a machining size thus controlling a route of feeding a machining tool. CONSTITUTION:If a machining tool diameter D and workpiece dimensions XA, YA are input from an input 3, the machining original point and a number of machining blocks Xi, Yi are determined, and if a measuring robe 2 is moved, a device measures by an instruction of a CPU1 the ruggedness height H of a machining surface in every divided block of matrix shape to be stored in a memory file 5b. Next, the device, whose arithmetic processing part 6 displays a cutting size of a Z-axis is an output part as the number of cutting times while stores the size in a memory file 5c as the cutting position distribution being classified by the height, controls the route of a machining tool being based on this distribution when a machining program memory 5a is executed. In this way, the device, preventing the machining tool from breaking, enables an overload on a driving motor to be avoided and the efficient machining to be performed.
