Programming
Table 3-2
Note 1: For the command addresses with functions (such as F, used for feedrate per minute, feedrate per
revolution and metric pitch and so on), they can be omitted not to input when executing the same
function to definite words after the words are executed. For example, after executing G98 F_ without
executing the thread command, the pitch must be input with F word when machining metric thread.
Note 2: They can be omitted not to input when the address characters X(U) , Z(W) are the coordinates of end
point of block and the system defaults the current absolute coordinates in X or Z direction to the
coordinate value of end point of block.
Note 3: The corresponding words must be input when the command addresses which are not in Table 3-2
are used.
Example 1:
O0001;
G0 X100 Z100; (rapid traverse to X100 Z100; the modal G0 is valid)
X20 Z30; (rapid traverse to X20 Z30; the modal G0 is not input)
G1 X50 Z50 F300; (linear interpolation to X50 Z50, feedrate 300mm/min; the modal G1 is
valid)
X100; (linear interpolation to X100 Z50, feedrate 300mm/min; Z coordinate is
not input and is the current coordinates Z50; F300 is kept, G1 is modal
and is not input)
G0 X0 Z0; (rapid traverse to X0 Z0 and the modal G0 is valid)
