Method for setting a machining feed rate and a machine tool using the same

A method for setting a machining feed rate of a machine tool for machining a workpiece portion to be machined by a machining means based upon a machining program, comprising the steps of:

• reading a data of the workpiece portion to be machined;
• segmentalizing the data into plural data points;
• determining a shape change point based upon a workpiece shape of the workpiece portion at each segmentalized data point;
• setting a machining feed rate for each shape change point with reference to a respective predetermined parameter corresponding to an attribute of each determined shape change point;
• and
• machining the workpiece portion based upon the set machining feed rate.

A method for setting a machining feed rate of a machine tool for machining a workpiece portion to be machined by a machining means based upon a machining program, comprising the steps of:

• reading a data of the workpiece portion to be machined;
• segmentalizing the data into plural data points;
• sectionalizing the workpiece using the segmentalized data points;
• classifying the sectionalized workpiece portion at each of the segmentalized data points as an area or a shape change of the workpiece shape;
• setting a machining feed rate for each area and for each shape change point with reference to a predetermined parameter corresponding to an attribute of each area and corresponding to an attribute of each determined shape change point;
• and
• machining the workpiece portion based upon the set machining feed rate.
