Cutter interference (or part surface gouging) is one of the most critical problems in NC machining of sculptured surfaces. Developed in this study is an algorithmic procedure for cutter interference handling that converts CC-data(cutter contact data; pairs of point and unit normal vector) into interference-free CL-data(cutter location data).

Recently 5-axis NC machines are widely used in Korea. Since 5-axis machines have two more degrees of freedom than 3-axis machines, it is very important to find desirable tool positions(locations and orientations) in order to make an efficient use of expensive 5-axis NC machines. In this research an algorithm to determine “optimal” tool positions for 5-axis machining of sculptured surfaces is developed. For given CC(Cutter Contact) points, this algorithm determines the cutter axis vectors which minimize cusp heights and satisfy constraints. To solve the optimal problem, we deal with following major issues: (1) an approximation method of a cusp height as a measure of optimality (2) Identifying some properties of the optimal problem (3) a search method for the optimal points using the properties. By using a polyhedral model as a machining surface, this algorithm applies to sculptured surfaces covering: overhanged surface.

This paper proposes a new approach for modeling sweep surfaces. The overall modeling procedure consists of following steps : (1)remeshing the section curves based on the curve lengths ; (2)remeshing the guide curve and the boundary curves based on a given sweeping rule ; (3)obtaining intermediate section curves at the remeshed points of the guide curve by blending the initial section curves ; (4)compensation of the intermediate section curves ; (5)interpolating the initial and intermediate curves using Hermite interpolant. The resulting sweep surface is expressed in a G$^{2}$ bicubic parametric spline surface.

The purpose of this study was to examine the structural relationship between the choice attributes, perceived values, customer satisfaction and loyalty of youth sports franchise customers, and determine if there is any difference in the structural relationship between the taekwondo gym and the swimming club. Toward this end, a total of 310 parents of the youth sports franchise members was selected using convenient sampling method, and 299 usable data were utilized in the data analysis. The results of this study were as follows. Firstly, program, accessibility and service sub-dimensions of choice attributes had significantly positive effects on perceived value, whereas facility and price sub-dimensions did not. Secondly, only service sub-dimensions of choice attributes had a positive impact on customer satisfaction. Thirdly, the service factor was only a significant determinant in predicting customer loyalty. Fourthly, perceived value significantly affected customer satisfaction. Fifthly, perceived value had a significantly positive impact on customer loyalty. Sixthly, customer satisfaction had a significantly positive effect on loyalty. Lastly, there were partial differences in path coefficients of the hypothesized model between the swimming and taekwondo gym members. Additionally, managerial implications and future research opportunities were also suggested.
