Background
When cutting plastic film, the contained angle between blade and the film has apparent influence to the cutting effect, and the selection of blade angle directly influences cutting quality. Harder materials generally require a greater blade angle to achieve better cutting results because a greater angle provides a stronger cutting force to penetrate and cut the material more effectively, and a smaller blade angle helps reduce cutting resistance and improves cutting efficiency at high cutting speeds. However, for applications requiring high precision cutting, a larger blade angle may be more suitable because it may provide a more stable cutting process, the blade angle not only affecting the cutting quality, but also affecting the cutting efficiency. The proper blade angle can ensure that the cutting process is smoother, and cutting resistance and blade abrasion are reduced, so that cutting speed and efficiency are improved, and the blade angle can also influence the abrasion condition of the blade. Improper blade angle may result in excessive pressure on the blade during cutting, thereby accelerating wear of the blade.
