Opis:: The present paper presents a method of determining errors in processing complex-shape surfaces produced with the use of a CNC machine tool. In order to achieve this, the whole process of making a three-dimensional object was performed, from creating a CAD model to generating a processing programme for a CNC machine tool and producing the actual object. The obtained surface was measured with a Brown & Sharpe Mistral coordinate measuring machine with the use of a Renishaw TP200 measuring probe.

Opis:: This paper presents the issues of coordinate measurements of three-dimensional objects whose shape is defined with the use of parametric surface description methods applied in CAD systems. The paper also describes a mathematical as well as a geometrical presentation of surfaces used CAD systems, and discusses coordinate measurement techniques applied in measuring objects of this class. Further in the article, a practical implementation of the methodology of reconstruct- ing objects described with the use of free-form surface patches has been presented. The methodology includes subsequent object measurements and reconstructing the object’s geometric model, and concentrates on the possibly most accurate reconstruction of the shapes and dimensions of the researched object.

Tytuł:: Machining Error Compensation for Objects Bounded by Curvilinear Surfaces

Opis:: The paper is devoted to topic related with machining error correction for objects bounded by curvilinear surfaces manufactured on numerically controlled milling machine. Currently it is realized by two techniques. The first of them is called on-line and requires continuous correction of toolpath during the machining process. This approach requires expanded adaptive control systems. The second method called off-line is based on correction of machining control system outside the machine (on the basis of control measurement results). This paper shows methodology of machining shape error correction with off-line technique (with no constant and direct connection to CNC machine tool). This method is based on usage of CAD/CAM systems, numerically controlled milling machine and coordinate measuring machine. Manner of procedure proposed in this paper was verified on the example of ruled surface profile described with NURBS technique. Realization of this proposed methodology of machining error correction has shown significant accuracy correction of manufactured element.

Opis:: The object of this paper is the implementation of boundary element method to solving the transient heat transfer problem with nonzero boundary condition and particularly with periodic boundary condition. The new mathematical BEM algorithm for two dimensional transient heat conduction problem with periodic boundary condition is developed and verified. The results of numerical simulation of transient heat conduction in two dimensional flat plate under non zero initial condition are compared with results obtained with analytical method. Then the practical application of developed algorithm is presented, that is the solution of ground temperature distribution problem with oscillating temperature of ambient. All results were obtained with a new authoring computer program for solving transient heat conduction problem, written in Fortran.
