Abstract
Za potrebe lesne industrije je potrebno izdelati 3 osni CNC stroj. Namenjen bo izdelavi lesenih izdelkov ter obdelavi mehkejših kovin. Iz zahtev končnega naročnika smo skonstruirali celotni stroj. Stroj je potrebno zagnati in testirati krmilnik, postprocesor ter uporabo CAM programske opreme. Ob končnem testiranju vseh funkciji smo preverili še natančnost stroj. To smo storili z Ballbar testom. S postopnimi iteracijami merjenja in programske kompenzacije pogreškov, ki jih je podal test, smo poskušali čim bolj izboljšati natančnost stroja. Po končanem umerjanju stroja smo CNC preizkusili še na dejanski aplikaciji in odrezali enostavni kos, na katerem smo opravili meritve. Meritve smo primerjali med modelom v CAD okolju in dejanskim izdelkom.

Title:Analysis of geometric precision and operation of 3 axis CNC machine in wood industry
Abstract:
For the needs of the wood industry, it is necessary to produce 3 axis CNC machines. It is intended for the production of wood products and the processing of softer metals. From the requirements of the final customer, we constructed the entire machine. We need to start the machine and test the controller, postprocessor and the use of CAM software. At the end of testing all the functions, we checked the accuracy of the machine. We did this with the Ballbar test. With the gradual measurement and program compensation errors, we tried to maximize the accuracy of the machine. After the calibration was completed, the CNC was tested on the actual application and cut off the simple piece on which we performed the measurements. The measurements were compared between the CAD model and the actual product model.

Keywords:CNC, control cabinet, finite element method, milling, main cutting force, servomotor, Ballbar test, servo drive
