Specifications and Procedures:
When cutting aluminum, it is recommended to use paraffin wax or paraffin. The cutting speed can be calculated using the formula: vc = (π x d x n) / 1000, where n is the speed in revolutions per minute and d is the tool diameter in millimeters.

Material Thickness and Hole Diameter Ratio:
The document discusses the importance of maintaining a specific ratio between material thickness and hole or punch diameter. Traditionally, the punch die should be equal to or larger than the material thickness. However, with ALFRA APS punching units, holes can be punched with a diameter smaller than the material thickness. A recommended ratio for punching in S235 steel is 1:1.3, with an upper limit of 1:1.7.
