Every metal or non-metal sheet acts in its own way when you cut it. First, check how thick and hard your material is. Use the right clearance percentage for the type of material. Softer metals like aluminum need a smaller gap. Harder metals like stainless steel need a bigger gap. Always test your settings on a scrap piece before you start your main job. If you see burrs or rough edges, change the clearance a little and try again. Sometimes you need to change the rake angle or move the blade for special materials. Write down what works best for each type. This helps you set up faster next time.<\/p><blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><strong>M\u1eb9o:<\/strong>&nbsp;When you use a new material, always reset your shear blade clearance adjustment.

If you feel any roughness, you need to change your settings. Compare the edges from different cuts. If all the edges look the same, your machine is set up well.
