自动对刀（Automatic tool setting） The so-called automatic tool setting is to automatically calculate the length of tools, diameter, size, and then automatically input data into the tool compensation table, in order to carry out parts processing. After careful study, analysis of its working principle, the author used the FANUC macro edit a macro program, and use a kind of homemade bar mounted to the chuck as a tool for cutting tool in this benchmark, benchmark and run a macro program, we can realize the automatic aligning instrument function. CNC lathe and CNC milling machine tool positioning in general more than 8, has reached 24, in the absence of automatic tool case, one by one with manual cut and try procedure, measurement, and then turn the manual calculation tool length and diameter, the numerical manually input to the tool compensation table is. A piece of work must be done before the processing of parts. But this method is inefficient, and manual calculation is prone to error, so its accuracy is poor, time-consuming and laborious, and directly affect the quality of products and production efficiency. To compensate for this, the author made use of Microset, by running the macro program make it to calculate the cutter length and diameter of the NC system, and then put it into the transmission tool compensation tables through the macro instruction, to realize the automatic aligning instrument of the accurate and efficient function. The details are as follows: the sample bar (Figure 1) is clamped on the hydraulic chuck, and the sample bar size is self determined and incorporated into the macro program. The macro program is as follows: O) _* {/ U; N1 @6 D3 (B J; V N1 G65 H01 P#500 Q#4120; put T code into #500 (G6, p#, s ~ t, U8} N2 G65 H05 P#511 Q#500 R100; #511 = #500 /100, remove the knife, the knife is used, No. No. K3 ^0 K6 # compensation = Q E7 FJ N3, G65, H02, P#511, Q#511, R2700, #511 = #511 + 2700, geometric compensated X bias n; E9 F* j ~2} w: H0]0 d q (N4 G6
