[0002] Railway engineering vehicles play a vital role in railway construction, maintenance, and related engineering operations. Their booms, as key components, bear important functions such as lifting and transporting. The machining precision and quality of the boom directly affect the performance and service life of the engineering vehicle. Traditionally, the machining of railway engineering vehicle booms involves a decentralized process, where each component is machined separately and then assembled. This method has several drawbacks:
