The working status of cutting tool is crucial to processing the product that gives high quality, how to undertake monitoring to cutting tool condition, discover damaged cutting tool in time, testing system of damaged of cutting tool of contact of Renishaw NC4 blame offerred convenient settlement way. Ducati company is in its engine production, creativity ground used unconventional Desmodromic system, the open of the valve in this system and shutting is to use special cam mechanism to undertake controlling, established the accurate connection between valve and cam position in each respects thereby. This kind allocates device to make engine runs next reliability in high speed stronger. Appearance of the cam in Desmodromic system used special ascendant brae, main purpose is to achieve the acceleration that systematic place needs and speed performance. In addition, likewise important is the assembly between component precision, this is a crucial operation. When this kind of special cam mechanism is being assembled, between lever and cam " clearance " move through the hand adjust, technical personnel uses handiwork to join a spacer each in cam bottom and coping, dominate the niche that good spacer adjusts below the condition in extremely tall precision. This kind of hydraulic pressure tappet that if rely on a car to go up,adjusts pattern is impossible to accomplish. The choice detects reasonably means 　 makes this kind of camshaft is a point-device job, and as a result of this kind of axis the precision with production very tall need, and it is by special type alloy steel material is made, cost is very high. So, if be in,cutting tool damaged appears in camshaft production process, that will cause very big loss. Ducati company realises the treatment of valuable spare parts in must controlling Desmodromic engine strictly. The most important segment in process of production of Ducati Desmodromic camshaft is finished on two Stama machining center. Between a year, these two machining center are uninterrupted movement, production is used at the camshaft of all sorts of Ducati engine. This among them all sorts of different cutting tool need to use by tens of thousands second, avoid very hard to take out the risk of craze or damaged cutting tool from inside knife library. Accordingly, must undertake to the damaged circumstance of cutting tool accurate detect. Ducati makes technologist Fulvio Abbondi express, "After purchasing a machine tool, we should install the testing system of main shaft power of former outfit on machine tool main shaft above all, can check older bit so (use at drilling the deepest hole) wear away degree, if main shaft torque increases, mean broach damaged, give out then call the police. But, some moment cutting tool can produce the damaged of a few minimum, and these damaged often can have escaped the examination of most testing system. " testing system of 　 traditional contact is support contact " pushbutton " or " lever " hind activation device will undertake detecting, put in a lot of blemish: 1.

In high speed treatment, osculatory itself is put possibly also in the risk that destroys cutting tool, must lower rate of cutting tool cutting so, but can make treatment cycle is lengthened greatly. 2.

Testing system must be installed normally inside work area, took up thereby valuable space, and the happening that causes collision hazard easily. Improve of the technology ceaselessly as laser, promoted the development that is not osculatory testing system. This kind of system can safety is measured than before smaller cutting tool. Light beam of a bundle of laser is mixed in emitter receiver (installation is in machine tool workbench or on its a side) between mobile, such beam of light can cross working area. When cutting tool crosses beam of light, the luminous flux that receiver detects decreases, then generation sparks pulse; If detect luminous flux did not decrease, the system issues signal of cutting tool damaged. Accordingly, ducati company passes serious analysis, discovery uses the Renishaw that is based on innovation laser technology to be not testing system of damaged of contact cutting tool, this one problem but be readily solved. System of Renishaw NC4 of testing system of damaged of new-style cutting tool is used at preventing damaged cutting tool to cause attaint 　 Renishaw NC4 to be not testing system of damaged of osculatory cutting tool to have to the spare parts to exceed small-sized laser emitter and receiver, norms is 30mm only (diameter) × 35mm (height) , can undertake in the occasion that cannot use before knife and cutting tool damaged detect be been not quickly osculatory is opposite. This system uses laser to detect to knife system damaged cutting tool, can make treatment process undertakes automatically, also won't bring about workpiece because of cutting tool damaged to discard as useless below the case that has cooling fluid even. After completing a treatment process, machine tool main shaft can carry cutting tool to cross the region of beam of light of this testing system on formulary height. If cutting blade damaged, criterion the luminous flux that receiver of beam of light receives will be changeless, then laser system can be given out call the police. Fulvio Abbondi expresses, "Use NC4 system, the damaged circumstance of the small cutting tool that we still can examine the key that is used on treatment cam and other datum mark, of this pair of engine move normally very crucial. If do not have this to cover a system, the machine tool may move below the circumstance of cutting blade damaged. In addition, because realized cutting tool,automatic damaged detects, the labor intensity that operates personnel also got alleviating greatly. " the person come true directly that installing the cutting tool of last word of testing system of Renishaw laser cutting tool outside area of machine tool work is metallic cutting treatment, below condition of cutting of contemporary high speed, cutting tool is very incidental damaged, if cannot discover in time, the new treatment that can cause a part perhaps discards as useless, bring a loss to the enterprise thereby. Renishaw NC4 blame contacts the occurrence of testing system of cutting tool damaged, offerred a kind for us handy, reliable detect means, the part that gives high quality for treatment thereby escorts the Emperor convoy.
