A. Support the program logic algorithm required for such things as PLC or CNC system or motion control card. A simple example is to solve the algorithm problem of an N-axis robot. Need to consider when the arm joint plane moves, the arm joint rotates, the elbow joint plane moves, the elbow joint rotates, the wrist joint rotates, and the knuckle swings. The equation of motion trajectory that all movements follow. (This type of calculation can be classified as a purely mathematical one, and physical things are not involved.)
B. Closely related to the calculation of physical phenomena. Such as statics, material mechanics, elastic mechanics, fluid mechanics.
When designing a part, first consider what task the part is to undertake or accomplish, and then combine these tasks to determine the shape of the part, determine the shape and the size of the motion relationship to be satisfied, and then apply the force state to the part. And the nature of the force and the material, taking into account the speed / thermal deformation / design life and many other factors, and finally to determine the shape and position size of each part.
C. Calculation of working hours and various process parameters for machining or assembly of parts or components. For example, in the manufacture of a certain equipment, the iron plate blanking part needs to be calculated for the iron plate discharge. The gold processing section has different calculations of processing parameters and calculations of different processing method arrangements for different processing properties. And the calculation of the processing time required for each step under such process parameters.
Recently, I have been working on a calculation device (CNC automatic saw blade grinding machine). The light is the function of solving the rotation angle/rotation speed of the saw blade and the displacement and the change rate of the grinding wheel. There are more than ten pages of A4 paper in the derivation part. content. (This is a first-class computational property) The calculation of the bearing capacity under different load properties of a certain type of equipment workbench and the determination of the resonant frequency of an elastomer are all calculated in the second category. Of course, the third type of property calculation can be summarized as a process category.
It is like practicing martial arts. If there is no internal training, even if it is a foreigner's move, it will never reach the level of the master. So a so-called real mechanical designer must be both internal and external. So what about our mechanical design counterparts who lack logical thinking? Yes, reverse! Just look from the back. Today's software technology and sensing technology are so developed. Many times we can avoid the complicated steps of calculation and verification. For a simple example, for example, you want to know the output torque of an output shaft at different speeds. Directly connect a torsion tester on the output shaft for each speed reading. The power factor of the motor, the friction between the transmission parts, the acceleration and the å’± caused by different masses and speeds of different transmission parts are all considered, so that the value read will be compared to the mode from the back to the rear. The calculated data is more accurate and effective.
