    Computer calculations
    In production, every machine operator would like to know how long the cutting tool will
 last until failure  or  complete  wear.  At  the  same  time,  operators  must  use  tools throughout
 their entire service life. Simulation for calculating tool life includes both simple calculations for
 individual operations and and the use of complex models using formulas with many variable
 parameters of the cutting process.
    Basic models allow you to manually and in a fairly short time to approximately calculate
 the tool life. More complex models require more calculations and more time. The best models
 allow very accurate tool life calculations. However, if the calculations for complex models take
 longer than the actual operations for which the calculations are performed, the economic benefit
 from them is questionable. Computer programs for calculations come to the rescue, allowing
 you to quickly and extremely accurately process numerous factors and parameters that are
 taken into account in complex models for calculating resistance.
