W artykule omówiono cel i zakres badania dokładności maszyn sterowanych numerycznie, w tym obrabiarek i robotów. Na tle dostępnych rozwiązań przemysłowych podano koncepcje patentowych rozwiązań oraz przedstawiono nową metodę, nazwaną wektorową z uwagi na wprowadzenie dodatkowego niezależnego układu współrzędnych. Omówiono wyniki badań laboratoryjnych oraz testy obrabiarek wykonane za pomocą dwóch przyrządów: do pomiarów w 2D oraz 3D. Wykonane testy wykazały przydatność przyrządu do badania dokładności obrabiarek NC.

The aim and scope of testing accuracy of NC machines including machine tools and robots were presented in the paper. Against a background of accessible industrial solutions there was presented idea for patents and new method, named vector method because of introducing new additional, independent coordinate system. There were presented results of laboratory tests and NC machines tests conducted with the use of 2D and 3D measuring instruments. These tests con-firmed usability of the instrument to measurements of accuracy of NC machines.

Purpose: In this paper the concept of automatic programs of the NC machine for metal plate cutting by genetic algorithm method has been presented. Design/methodology/approach: The paper was limited to automatic creation of NC programs for two dimensional cutting of material by means of adaptive heuristic search algorithms. Findings: Automatic creation of NC programs in laser cutting of materials combines the CAD concepts, the recognition of features and creation and optimization of NC programs. The proposed intelligent system is capable to recognize automatically the nesting of products in the layout, to determine the incisions and sequences of cuts forming the laid out products. Position of incisions is determined at the relevant places on the cut. The system is capable to find the shortest path between individual cuts and to record the NC program. Research limitations/implications: It would be appropriate to orient future researches towards conceiving an improved system for three-dimensional cutting with optional determination of positions of incisions, with the capability to sense collisions and with optimization of the speed and acceleration during cutting. Practical implications: The proposed system assures automatic preparation of NC program without NC programer. Originality/value: The proposed concept shows a high degree of universality, efficiency and reliability and it can be simply adapted to other NC-machines.
