A point ‘P’ is moved to another point ‘Q’ using the coordinate system shown in the figure below and the rapid positioning command (G00). The table on the X-Y plane is controlled by the CNC machine.
Two stepping motors M1 and M2 with a maximum speed of 700 rpm are controlling the X and Y motion of the table, respectively. The shaft of the motor M1 is directly coupled to a lead screw of the pitch as 0.4 mm and the shaft of the motor M2 is directly coupled to a lead screw of the pitch as 0.6 mm. The time needed to position the point ‘P’ to the point ‘Q’ is ______ (round off to 2 decimal places).
