Mathematical Formulas for Optimal Use

• Pressing Force (F): Calculated as: F=P×AF = P \times A $F$ $=$ $P$ $\times$ $A$ Where:

  • PP $P$ is the applied pressure in tons.
  • AA $A$ is the contact surface area in mm².

• Working Speed ​​(v): Determined by distance and cycle time: v=DTv = \frac{D}{T} $v$ $=$ T D ​Where

  • DD $D$ is the distance traveled in mm.
  • TT $T$ is the time taken in minutes.
