Procesni tehničari dodjeljuju montažne jedinice prema cjelokupnom montažnom crtežu, crteži podsklopa, i pojedinačni dijagrami dijelova proizvoda. To rezultira formiranjem jedinica za sklapanje komponenti, jedinice za sklapanje delova, i na kraju kompletna konačna montaža.
Sub-Assembly
A component assembly unit comprises a combination of multiple distinct or identical parts (and composite types) assembled together. This procedure is termed “sub-assembly.”
Part Assembly
A part assembly unit is formed by assembling a variety of different or similar parts (and elements) together. The process of assembling these units is referred to as “part assembly.”
Final Assembly
The final assembly constitutes the equipment’s complete assembly, involving the combination of various distinct or similar parts or components (and elements). This stage is known as “final assembly.”
In the allocation of assembly units, a specific part should be identified as the reference component, which becomes the baseline for installation. Other parts may also serve as reference components for the installation of subsequent elements. Idealno, a reference component should be large, heavy, and provide ample space for assembly, thereby aiding in the efficiency of later assembly tasks. Na primjer, the body of an razvodna kutija otporna na eksploziju could be used as a reference component.
