[0002] At present, gas cutting bevels are cut by manual gas cutting or semi-automatic cutting machines, but semi-automatic cutting machines are limited to straight-line cutting of bevels. For angled curved bevels, manual gas cutting has always been used. When manually cutting curved bevels, the gas cutter's operation will be affected by many external factors (wind, working environment, physical factors). The operator needs to frequently adjust the working posture and the inclination angle of the cutting nozzle, resulting in different quality of each product. Manual gas cutting of curved bevels is to manually mark the bevel position line for each piece, and then adjust the cutting nozzle to the required inclination angle to perform gas cutting bevels. A single product requires three processes to complete, which is inefficient and labor-intensive. Summary of the invention
