【正文】 ting, the radial direction cutting force death of a parent is not suitable for to process the tall and slender work piece very much. The vibration cutting is along the cutting tool direction of feed, the attachment low frequency or the high frequency vibration machining, may enhance the cutting low frequency vibration cutting has the very good chip breaking effect, but does not use the chip breaking equipment, makes the knife edge intensity to increase, time the cutting total power dissipation pared to has the chip breaking installment ordinary cutting to reduce about 40%.The high frequency vibration cutting also called the ultrasonic wave vibration cutting, is helpful in reduces between the cutting tool and the work piece friction, reduces the cutting temperature, reduces the cutting tool the coherence attrition, thus the enhancement cutting efficiency and the processing surface quality, the cutting tool life may enhance 40% approximately. To lumber, plastic, rubber, glass, marble, granite and so on nonmetallic material machining, although is similar with the metal material cutting, but uses the cutting tool, the equipment and the cutting specifications and so on has the characteristic respectively. The lumber product machining mainly carries in each kind of joiner39。 The outer annulus and the end surface may use the negative rake the hard alloy lathe tool, by 10~30 meter/minute cutting speed turning。 The big stone material plane available hard alloy planing tool or rolls cuts planing tool shaping。s cutting edge of blade to the crushing and cutting depth of the trench lines badly worn. But using the latest hightemperature processing of small particles hard metal alloys to be effective, cutlery life improved, but more importantly to enhance the reliability of applications in hightemperature alloys. Small particles hard metal than traditional hard metal materials higher pression strength and hardness, only a small increase in the resilience of the cost. And resulted in high temperature alloy processing than traditional hard metal resistance mon failure mode more effective.PVD (physical gas phase deposition) coating also by certificate effective processing heatresisting alloy. TiN (titanium nitrides) the PVD coating was uses and still was most early most receives wele. Recently, TiAlN (nitrogen calorization titanium) and TiCN (carbon titanium nitrides) the coating also could very good use. In the past the TiAlN coating application scope and TiN pared the limit to be more. But after the cutting speed enhances them is a very good choice, enhances the productivity in these applications to reach 40%. On the other hand, is decided under the low cutting speed in coating superficial operating mode TiAlN can cause to accumulate the filings lump afterwards, micro collapses with the trench attrition.Recently, used in the heatresisting alloy application material quality already developing, these coating but became by several binations. The massive laboratories and the scene test has already proven this kind of bination and other any kind of sole coating pares in time the very wide scope application is very effective. Therefore aims at the heatresisting alloy application the PVD pound coating possibly to bee the focal point which the hard alloy new material quality research and development continues. With the MTCVD coating, the coating ceramics gather in the same place, they hopefully bee a more effective processing to research and develop newly are more difficult to process the work piece material the main impact strength.Dry processingIncluding the refrigerant question is technical and the mercial expansion industrial production tendency another domain which the cutting tool makes. North America and the European strict refrigerant management request and the biggest three automobile manufacturer forces them the core supplier to obtain the ISO14000 authentication (the ISO9000 environment management edition), this causes the refrigerant processing cost rise. To the car pany and their core supplier said obviously one of responses which wele is in the specific processing application avoids pletely the refrigerant the use. This kind did the processing the new world to propose a series of challenges for the cutting tool supplier.Recently, already appeared some to concern this topic to promulgate the speed, to enter for, the coating chemical position and other parameters very substantial prehensive nature very strong useful technical papers. Wants to concentrate the elaboration in here me does the processing viewpoint in the operation and mercial meaning automobile manufacturer new.The metal working jobholders can the very good understanding related refrigerant use question, but majority cannot understand concerns except the technical challenge (for example row of filings) beside does the processing question in the cutting tool work piece contact face between. Usually may observe to the refrigerant disperser scrap which flows out, but the pressure surpasses 3,000 pounds/An inch 2 high speed refrigerant also can help to break the filings, specially soft also the continual scra
