金属板材在经过刨槽工艺后，折弯回弹虽然大幅降低，但仍然存在。因此在刨V

After the metal sheet undergoes the grooving process, although the bending springback is greatly reduced, it still exists. <br>Therefore, when planing the V-shaped groove, we must flexibly groove according to the bending angle of the workpiece. <br>Let's take the stainless steel sheet as an example again: <br>the opening angle of the V-shaped groove is 1°～2° larger than the bending angle. <br>For a workpiece with a 90° forming angle, the V-groove grooving angle is generally 92°. <br>This can well avoid the angle error caused by the bending springback.

After the metal sheet has been plowed, the bend rebound is greatly reduced, but it still exists.<br>Therefore, when cutting the V-shaped groove, we have to be flexible in grooving according to the bend angle of the work piece.<br>Let's take the stainless steel sheet again as an example:<br>The slotting angle of the V-slot is 1 to 2 degrees larger than the angle of bend forming.<br>A work piece with a forming angle of 90 degrees, and its V-slot slotting angle is generally 92 degrees.<br>This is a good way to avoid angle errors caused by bend bounces.

Although the springback of metal sheet after grooving process is greatly reduced, it still exists.<br>Therefore, when planing the V-shaped groove, we should flexibly slot according to the bending angle of the workpiece.<br>Once again, we take stainless steel sheet as an example<br>The slotting angle of V-groove is 1 ° to 2 ° larger than that of bending.<br>For a workpiece with 90 ° forming angle, the V-groove slotting angle is generally 92 °.<br>In this way, the angle error caused by springback can be avoided.<br>
