The basic cause of constant error occurring in lathes is the inaccurate setting of the tool. ... The simple character of these diagrams is due to the assumption that variations in functional errors follow a linear law and that the scatter in the random errors is constant with time. ... The line 1 denotes the constant errors; broken lines 2 and 4 are the distribution limits of the random error; continuous line 3 is theanbsp;...
