Leveling (manufacturing process)
Leveling is the processing of a workpiece with the aim of making it evenly flat ( planar ), especially between two flat tool surfaces, but also other processes. Leveling refers to the workpiece geometry, not the surface. Flat workpieces can, but do not have to be, smooth.
Leveling is a forming process . Both semi-finished products and as an intermediate production step are leveled , for example to correct material tension in previous work processes. Such methods are also used in repairs . Leveling is primarily important for flat workpieces, especially sheet metal , but also paper and cardboard materials .
Can be leveled by the following manufacturing processes :
- Alignment, flatness
- directional shape
- Smoothing (fine grading)
- Schedule drive (leveling by material thinning whole with any ex post blank)
- Upsetting (leveling through material thickening, with large-area correction of dents)
- Tighten
Typical flat tools are for example rollers (or calenders for paper) or hammers . A hand tool is the planing hammer ( straightening hammer ), which is used in thin sheet metal work. Here, through expert application, shaping, driving and upsetting blows are combined to produce flat workpieces.
