This paper describes state-of-the-art manufacture of ship propeller blades with numerically controlled(NC) machining. A brief explanation of the rationale for NC machining is provided, followed by a discussion of the operating experience of a blade machining center over the past six years. Some of the unique considerations involved in the NC programming and machining processes are described along with some of the most common production problems. The factors leading to the company's decision to expand the blade machining center are discussed along with a description of the design and procurement of the new equipment and facilities. Tolerances achieved by NC machining and hand finishing are compared.

Our country is manufacturing industry power in the world, NC machining is used in mechanical manufacturing industry widesprealy. With the development of manufacturing industry, NC machining strides forward super-speed machining step by step. In order to achieve the machining requirement of speediness and high-precision of complex parts, automatic programming becomes the main programming pattern of NC programming. Ensuring validity and optimizing of NC programs is fundamental demand of automatic programming. So as to test validity and optimizing of NC programs, NC simulation is obtained widespread use in the process of programming.

Assembly Principles

Applying DFMA (Design for Manufacturing and Assembly) principles is crucial in the process of designing models for wind tunnel testing. The design process, especially of models for measuring the pressure distribution, takes several months. Production of these models require a minimum couple of months; sometime even more. The manufacturing with defects are not allowed. Very narrow time limits, defined by a contract, do not leave enough time for reworking. Very often, designers may not have knowledge of manufacturing rules and best practices - resulting in slower product development cycles, increased ECO/MCO (Engineering Change Order / Manufacturing Change Order), significant material waste and lower production yields. Manual reviews of Design or consultations with manufacturing experts are time consuming. Whole process need for proximity between design and manufacturing engineers. Design engineers need quick and interactive feedback while designing, integrated access to company’s manufacturing knowledge repository. This paper presents an automated application DFMA principles, applying the rules defined in the prototype production of wind tunnel models in Military Technical Institute.

The grinding for cylindrical cam’s groove means grinding for groove’s flanks. For cylindrical cam with translating cylindrical followers, an auto-programming system for NC machining of cylindrical cam’s groove is developed. It can be applied to machine cylindrical cam with different types of curve grooves, by using cutter or wheel with different diameter. For validating geometry precision of the auto-programming system, emulation is carried out using the VERICUT, which is a NC machining emulator system. It is showed by the results of the emulation, there is excess of geometry error at bottom of groove when following situations are met: big pressure angle, high precision requirement and big diameter difference between wheel and roller. An important origin of such excess is computational error introduced by the auto-programming system in calculating the coordinates of wheel center.

Intersection Points

Approximate Double Circular Arc Interpolated Method (ADCAIM) has been proposed by the authors. It requires only the included angles in the normal directions of the adjacent arcs at intersection points to be less than specified value, but does not require the adjacent arcs to be tangent as in other circular arc interpolated methods. ADCAIM is an approximate method with better calculating speed because of its concise calculation, and its interpolated error can meet the requirement too. The problems in NC programming of aspheric curves have been solved by using ADCAIM. In this paper, to the plane profile including aspheric curves, using VB program language as the second development tool, auto-programming for NC machining of aspheric curve is also realized by using ADCAIM, as long as the curve’s profile graphics on the AutoCAD is known. The research result indicates: the method introduced in this paper can meet the needs of NC machining in both interpolated accuracy and calculating speed for the example.

From that, the real-time and parallel simulation in the whole process of NC machine tool’s design and manufacture would be achieved. Along with the all-sided expanding of digitized technology in the design field of NC machine tool, the corporations’ colligation which includes design, manufacture and management would be greatly upgraded and the development of entire manufacture will be expedited. And the mechanical equipments’ design and manufacture will be promoted at a larger-scale.
