5. FEED FUNCTIONS
NC FUNCTION
85
Move command in blocks commanded with G09 decelerates at the end
point, and in–position check is performed. G09 command is not
necessary for deceleration at the end point for positioning (G00) and
in–position check is also done automatically. This function is used when
sharp edges are required for workpiece corners in cutting feed.
Exact stop on (The in-position
check is performed at the end of
a block.)
Exact stop off
When G61 is commanded, deceleration of cutting feed command at the
end point and in–position check is performed per block thereafter. This
G61 is valid till G64 (cutting mode), G62 (automatic corner override), or
G63 (tapping mode) is commanded.
When G64 is commanded, deceleration at the end point of each block
thereafter is not performed and cutting goes on to the next block. This
command is valid till G61 (exact stop mode), G62 (automatic corner
override), or G63 (tapping mode) is commanded.
When G63 is commanded, feed rate override is ignored (always regarded
as 100%), and feed hold also becomes invalid. Cutting feed does not
decelerate at the end of block to transfer to the next block. And in-tapping
signal is issued during tapping operation. This G63 is valid till G61
(exact stop mode), G62 (automatic corner override), or G64 (cutting
mode) is commanded.
When G62 is commanded during cutter compensation, cutting feed rate
is automatically overridden at corner. The cutting quantity per unit time
of the corner is thus controlled not to increase. This G62 is valid till G61
(exact stop mode), G64 (cutting mode), or G63 (tapping mode) is
commanded.
