WATER JET MACHINING METHOD FOR HARDLY MACHINABLE MATERIAL

PROBLEM TO BE SOLVED: To provide a machining method causing a machined surface to be smooth even when a workpiece being an object has a small diameter without generating burr or bending and without generating an excessive cutting flaw or the like to another part, in the machining method of cutting t...

description	PROBLEM TO BE SOLVED: To provide a machining method causing a machined surface to be smooth even when a workpiece being an object has a small diameter without generating burr or bending and without generating an excessive cutting flaw or the like to another part, in the machining method of cutting the workpiece of a pipe shape formed of a hardly machinable resin such as an engineering plastic or a hardly machinable material such as a composite material using inorganic fiber using a water jet.SOLUTION: An apparatus provided with an impact absorption means inserted into a hollow part of a workpiece to absorb impact by a water current of an injected water jet is used. Cutting machining of a product member having a predetermined size is sequentially performed from an end of the workpiece at a side confronting a support means. A rotational speed of a rotation means and a pressure of the water jet injected by an injection means are adjusted. The cutting proceeds with a cutting depth of ≤0.5 mm during one revolution of the workpiece to perform the cutting.
