We can use two different G-Codes to apply cutter compensation depending on the direction of the cut. G41 is left compensation and G42 is right compensation. On a CNC machine, it is usually recommended to use climb milling, this needs to be taken into consideration when writing our programs and deciding which direction to apply cutter compensation.

As the HGI ball mill works on the same principle as pulverizing mills, the index obtained from this could give a fair assessment of the grinding capability of torrefied biomass. For biomass, one should use ( Agus and Waters, 1971; Joshi, 1979 Agus and Waters, 1971 Joshi, 1979 ) a standard volume of sample instead of mass to compare the grinding ease to coal and torrefied …
