Introduced systematically the forming principles and mathematical modeling of grinding/ milling spiral flutes with numeric control machines, overviewed the functions of multi-axis linkage and the determination technique of the number of the linkage axes, discussed the conversion technique of NC—STEP-NC code in programming with EXPRESS, presented advances of controlling systems with high performance. Much attention was paid to the explanation of the error modeling and the tool interference in the real machining with the error-compensation techniques. Trends were envisioned on key technique study of the forming principles for the spatial spiral flutes, function of multi-axes, tool interference in the real machining and simulation of the operation processing, as well as automatic generation of NC codes and the connection /compatibility of the codes with the mainline NC systems, in future.

A new machining feature model for cylinder-type parts is proposed. Through the use of the model in process planning, the NC program can be generated by modular approach. NC machining feature classification based process design method is a good solution to the integration of the traditional and NC processes. With the machining feature as unit, parametric programming technique is applied to the NC code generation which can improve the efficiency and quality of the NC program design. The proposed method has been practically demonstrated in the enterprise information system.

The processing of rough machining and semi-finishing of revolving body stone is studied, according to the particularity of stone machining. Based on the study of processing, the system of computer aided programming and simulation for the revolving body stone is mainly researched. This system integrates the NC code automatic generation module and numerically controlled machining simulation module and this system is able to verify the pre-existing NC code. Thus greatly improves the efficiency and raises the quality.

Abstract. The Simon effect lies on the automatic generation of a stimulus spatial code, which, however, is not relevant for performing the task. Results typically show faster performance when stimulus and response locations correspond, rather than when they do not. Considering reaction time distributions, two types of Simon effect have been individuated, which are thought to depend on different mechanisms: visuomotor activation versus cognitive translation of spatial codes. The present study aimed to investigate whether the presence of a distractor, which affects the allocation of attentional resources and, thus, the time needed to generate the spatial code, changes the nature of the Simon effect. In four experiments, we manipulated the presence and the characteristics of the distractor. Findings extend previous evidence regarding the distinction between visuomotor activation and cognitive translation of spatial stimulus codes in a Simon task. They are discussed with reference to the attentional model of the Simon effect.
