Notes
：
●
ns block is only G00, G01. When the workpiece is type II, the system must specify the two
axes X(U) and Z(W), and W0 must be specified when Z does not move;
● For type II, only X finishing allowance can be specified; when Z finishing allowance is
specified, the whole machining path offsets, and it can be specified to 0;
●
For type II, after the current grooving is completed to execute the next, the tool approaches
the workpiece(remark 25 and 26) in the remainder tool retraction distance at G1 speed; when
the tool retraction is 0 or the remainder distance is less than the tool retraction, and the tool
approaches the workpiece at G1 speed;
● Some workpiece without remarking the type I or the type II adapts the both;
● For the finishing path(ns ～ nf block) ， Z dimension must be monotonous change(always
increasing or decreasing), X dimension in the type I must be monotonous change and does
not need in the type II;
● ns ～ nf blocks in programming must be followed G71 blocks. If they are in front of G71 blocks,
the system automatically searches and executes ns
～
nf blocks, and then executes the next
program following nf block after they are executed, which causes the system executes ns ～ nf
