| Abstract: | The common equation for transforming nozzle spray - hole design angle to process and test angle was obtained by means of solid geometry and trigonometric function in this paper. In addition, the equation for machining error was obtained using differential calculus, the result was validated by the method of limit deviation, as well as, application was given an exam- pie. General speaking, the date shows agreement with each other. The process is easy to grasp and suited to design all kinds of long nozzle spray - hole. |
