[0002] In the construction of offshore oil platform topsides and land modular factories, holes need to be cut again to insert pipelines or cables. Traditional manual hole cutting requires on-site hole positioning, manual drawing of the size template of the cut hole, and pre-judgment and polishing of the cut part in advance. The size template of the cut circle is manually drawn as the cutting line for cutting.

[0003] Traditional manual hole cutting techniques vary, and flame cutting and plasma cutting will generate high temperatures, which will affect the integrity of the drawn lines. When cutting larger holes, it is impossible to find a suitable reference, so it takes more time. Manual cutting will produce corresponding errors. At the same time, manual cutting will damage the parent material, which will greatly increase the subsequent grinding and welding volume, and the cost will also increase relatively. This causes limitations in the selection of personnel and the size standards for cutting round holes cannot be unified.
