Kutsirizitsa kosalala kopangidwa ndi makina kumapanga malo okhala ndi masamu amatanthawuza roughness, omwe amadziwikanso kuti Ra, a 1.6 μm (63 μin).Monga kumalizidwa kopangidwa ndi makina, kumaliza kosalala kopangidwa ndi makina kumaperekanso kuchotsa m'mphepete ndikuchotsa mbaliyo.Popeza kuti pamwamba pake ndi yosalala kuposa momwe amamaliza, zizindikiro zake ndi zofooka sizimawonekera.Kumaliza kosalala kopangidwa ndi makina sikupezeka ndi zodzikongoletsera.

Zigawo zina zimafunikira kumaliza kosalala kuposa komwe kumaperekedwa ndi kumaliza kokhazikika.Zikatero, ntchito yowonjezereka yopangira makina ikuchitika kuti achepetse roughness pamwamba pa mtengo wovomerezeka.M'madera opangidwa ndi makina a CNC, ntchito zoterezi zimatha kuwonjezeredwa pakupanga kuti zisunge nthawi.Kwa magawo opangidwa ndi makina omwe si a CNC kapena makina angapo, makina a CNC amagwiritsidwa ntchito popanga makina osalala atatha kupanga ndipo gawo lakonzeka.
