The work efficiency can be improved if we work out macro program in the practical processing according to the real parts. Through the study of the macro program of FANUC 0i system, based on the macro programming, combining the characteristics of the hyperboloid of two sheets, the thesis develops manual programming of milling double hyperboloid methods with the adoption of hierarchical milling and linear approximation oval. And corresponding application example is also given out in the paper. The method is of simple programming with small programming capacity and highly optimized for general use, which also has certain significance for the space complex surface machining.

Swept Volume

In this paper, a novel approach of linear octree is employed to represent discrete tools and build their swept volumes along machining trajectories. Firstly, a data structure of linear octree is defined as the base of geometrical transformations. The linear octree can be extended into leaf nodes in the deepest level for simplifying homogeneous transformations, and all leaf nodes in the deepest level can also be concentrated into a linear octree for saving storage capacity inversely. Secondly, tool trajectories are interpolated as short lines, and swept volumes between neighbor interpolation points are defined as the Minkowski sum of their cell sets at both locations. Thirdly, equations of the rotation matrix for local coordinate system, roll, pitch and yaw angles of tool orientations are established to define the global rotation motions. Finally, a case of discrete sphere tool and its swept volume modeling are studied to validate the proposed approach.

A high-performance and accurate machining of complex special surfaces with the aid of NC equipment at the simultaneous use of four and more controlled coordinate axes is impossible without application of modern CAD systems and post-processors. Functional potentialities and a methodology for the design of complex surface machining in a "flange" part in modern CAD Esprit system are considered. Control commands are described the realization of which ensures a procedure for a computer aided design of technology, the development of a control program and simulation of operation motions of working units in a lathe. The simulation of profile surface turning is described in an intelligible way which is particularly significant for the comprehension and use of material presented.

An accurate method to calculate the section line of the complicated surface after numerical controlled machining is presented in this paper. The method to calculate the tooth surface of the conjugate gearing is applied into the field of sculptured surface machining. It is the most precise method to determine the remaining scopes on the surface. The calculated remaining scopes are exact the same as that in practical cutting. The concept of contact is applied into the machining of the complex surface. If the contact line along the straight line of cutter, the contact line should along the asymptotic direction of the surface being machined. For the undeveloped ruled surface, the directions of the normal vectors are different, while the directions of the normal vectors on the straight line of cylinder are the same, so that there may be some over cutting on the surface. With the theory of this paper, the best cutter postural can be determined when the contact line not along the straight line of the cutter. And further more, with the concept of third order contact, both the best cutter postural and contact direction can be determined at same time.
