What you said is too general. The general process of designing mechanical equipment is: 1. Set plan (function, space, structure, etc.); 2. Draft project (project classification, division of labor, schedule plan, cost budget, etc.); 3. Specific Implementation (the specific design of the mechanical part, the design of the electrical, hydraulic, and pneumatic parts, of course, if your equipment needs these areas); 4, improvement and modification; 5, trial operation. I said it in general, and I hope it will help you.
