Ihiwalay ang machine capability sa finished-member tolerance
Ang 30 kW laser equipment ng Jiangxin ay para sa plate at profile cutting, na may plate capacity hanggang 60 mm. Ang 0.01 mm ay positioning accuracy ng motion system. Hindi ito blanket claim para sa cut-edge quality, hole-position deviation o tolerance ng welded finished member. Nakabatay pa rin ang acceptance sa drawings at dimensional inspection.
Nesting, piercing at heat input
Dapat isaalang-alang sa nesting ang material grade, thickness, rolling direction at piece marks. Naaapektuhan ng part spacing, lead-ins, piercing positions at small holes ang material yield at cut stability. Para sa thick plate, kailangang balansehin ang power, speed, focus, nozzle at assist gas. Nakakatulong ang cutting sequence, skip cutting o zoned cutting upang mabawasan ang heat concentration at plate movement.
Bevels at process allowances
Dapat tukuyin ng fabrication drawing ang bevel angle, root face, root gap at processing method. Kailangan ding isama sa cut dimensions ang allowances para sa fit-up, weld shrinkage at straightening; hindi kapalit ng mga allowance na ito ang positioning accuracy.
First-article inspection at process selection
Sinusuri sa first-article inspection ang material, thickness, dimensions, hole groups, cut squareness, dross, heat-affected condition at piece marks. Kapag approved na, saka inilalabas ang nesting file at parameters para sa batch. Ang CNC flame o plasma cutting ay maaari pa ring mas angkop para sa plate na lampas sa effective laser range, malalaking blank, ilang bevel arrangement o high-throughput rough cutting. Dapat timbangin ang edge quality, downstream work, production rate at cost.
