<p>An optimum cutting fed rate of a machine tool is calculated at the outset and a tool path as well as the optimum cutting feed rate calculated is to be directly output to a driving unit of the machine tool. A relative movement between the work and a tool is to be made to occur along the tool path at the optimum cutting feed rate for each part of the tool path. To this end, a control system is provided that includes a CL data generating unit 32, a CL data memory 33, a driving capability data memory 34, a cutting feed rate data generation unit 35, a cutting feed rate data memory 36, and a controller 42. The CL data generation unit generates CL data, inclusive of the tool path, based on shape data, and the CL data memory memorizes the CL data. The driving capability data memory pre-stores driving capability data regarding the driving capability of the driving unit 6 of the machine tool 4. The cutting feed rate data generation unit generates cutting feed rate data in each part of the tool path of the CL data based on the CL data and the driving capability data. The cutting feed rate data memory memorizes the cutting feed rate data. The controller outputs the CL data and the cutting feed rate data to the driving unit 6</p> |
