In the process that makes product part in machine tool of applied numerical control, the factor that affects spare parts quality is very much, among them, the accurate setting of cutting tool parameter all the time since get attention rarely however, and the size scope that should ask workpiece treatment to craft is contented form tolerancepublic errand requirement, parameter of accurate setting cutting tool is one of main demands. It is to use a setting to be in to knife means inside machine machine tool workbench the measurement unit on the face (to Dao Yi) , to knife library medium cutting tool undertakes metrical by set program, undertake comparative with referenced position or standard knife next, get the length of cutting tool or diameter, in updating parameter of corresponding NC cutting tool automatically to express. Using pair of Dao Yi to undertake is accurate to the main good point of the knife inside machine, automatic, real time, do not have technical requirement to handlers; Defect is to need alone configuration to measure a head to the knife. Inside the to Dao Yi classification inside machine and applied limits machine general to Dao Yi by sensor, signal interface and to Dao Hong program software is comprised. According to sensor work way, can divide to Dao Yi inside machine be opposite to Dao Yi and laser for contact Dao Yi two kinds. Among them contact is right of knife appearance oneself repeat measure precision to be 1 μ M. What the basis transmits means to knife appearance signal is different, can farther fractionize is the following kinds. (1) cable formula is right to type of Dao Yi cable Dao Yi (the TS35 that is like Haikesikang.

10 pairs of Dao Yi) because do not need the changeover part of pair of knife signal, and have first-rate sheet sexual price is compared, because this is most common in the job, but its defect is the daggle that has cable, restricted its to use an occasion, the 3 axes milling machine of small norms in basically be being applied to / machining center. (2) infrared formula is right to type of Dao Yigong exterior line Dao Yi (the IRT35 that is like Haikesikang.

70 pairs of Dao Yi) signal transmission limits is in commonly 6m less than. Its advantage is to use the data of HDR(high speed of encode to transmit) infra-red technology, avoided the inconvenience that cable daggle brings and potential insecure factor thereby, to can getting off from workbench face at any time after the knife, do not take up treatment space, and can much stage machine tool is common 1 to Dao Yi, can reduce integrated cost thereby. Its defect is when be used on small-sized machining center sexual price is compared not tall. By its the characteristic is decided, this kinds multi-purpose to Dao Yi establish a car to wait at medium-sized machine tool and large numerical control. (3) radio type to Dao Yi radio type is opposite Dao Yi (the RWT35 that is like Haikesikang.

50 pairs of Dao Yi) radio signal transmission limits is in commonly 10m above. Its advantage is radio signal transmission range is big, and be affected not easily by the environment, to can getting off from workbench face at any time after the knife, do not take up treatment space, and can much stage machine tool is common 1 to Dao Yi, can reduce integrated cost thereby. This kinds multi-purpose to Dao Yi at large / heavy-duty / machine tool. (4) laser is right to Dao Yi laser Dao Yi (the LTS35 that is like Haikesikang.

60 pairs of Dao Yi) fundamental sparks to use focusing laser light beam to be agency, when the cutting tool that is rotated when laser light beam is obstructed, arise namely spark signal. Laser uses blame contact to measure to Dao Yi, be opposite force was not contacted when the knife, can undertake metrical to extremely petty cutting tool, and because contact mechanical responsiveness to send petty cutting tool to fold caustic,need not worry, be like LTS35.

It is OK that 60 pairs of Dao Yi can measure cutting tool diameter small to 0.

008mm, oneself repeats measure precision to achieve 0.

2 μ M. In the meantime, because measure when, cutting tool rotates with machining speed high speed, measure condition to be equal almost completely so at machining condition actually, raised the practical precision to the knife. Because use laser technology, this pairs of Dao Yi can undertake scanning to cutting tool appearance, measure the outline of cutting tool, can undertake to the single the crucial point of multiple-cutting-edge tool damaged is monitored. Main drawback is a structure more complex, need additional configuration high quality to enrage a source to undertake protective to internal composition, cost is higher, basically apply to high speed machining center. The to Dao Yi common function inside machine and advantage (1) cutting tool length / measure automatically of the diameter and parameter updates: Length undertakes when cutting tool is turning / diametical trends is measured; In the meantime, can undertake be metricaled automatically of cutting tool parameter at any time, thereby great because machine tool heat is out of shape,eliminated of the cutting tool parameter that cause " change " ; In measuring the parameter that updates corresponding cutting tool automatically as a result to express. (2) cutting tool wears away / the automatic monitoring of damaged: Can be to Dao Yi inside use machine before library of knife of the replace after cutting tool treatment ends, undertake automatically metrical to cutting tool length, when if happen,wearing away normally OK and automatic will wear away several watch arrive newly in knife caustic parameter, if produce train in excess specified length to wear away,can regard as cutting tool damaged (break off) , choose to change thereby the treatment that new knife has next work stops automatically perhaps machine call the police clew handlers undertakes cutting tool changes. (3) machine tool hot metabolic compensates automatically: Be opposite inside use machine after Dao Yi, in the process perhaps is being machined before can be being machined, undertake be measured automatically and be updatinged to cutting tool parameter at any time, be being measured every time is the cutting tool setting that has below condition of hot metabolic of current machine tool. (4) the measurement of cutting tool outline and monitoring: In a few special treatment (if use,shape cutting tool is machined) , the laser inside use machine can be used at any time to Dao Yi stimulate scanning of beam of light to measure or outline of monitoring cutting tool, update automatically according to what need undertakes corresponding parameter, assure the final precision of workpiece.
