1. G Function Description
TYPEⅢ: General Peck Tapping (Custom Parameter No.4001= 0)
Description:
1. Use G00 to positioning to specified (X, Y) when start to perform.
2. Use G00 to reach specified point R.
3. Use G01 to interpolate a distance Q at the present depth.
4. Dwell P(s) and reverse the tap. Then use G01 to reach point R.
5. Dwell P(s) and reverse the tap. Then use G01 to interpolate a
distance “Q” relative to the depth of present hole.
6. Dwell P(s) and reverse the tap. Then use G01 to reach point R.
7. Repeat the above action until reaching the bottom of the hole,
point Z.
8. Dwell P(s) and reverse the tap. Then use G01 to rise to point R
(G99).
9. Dwell P(s) and reverse the tap. Then use G00 to rise to initial
point (G98).
tapping pitch/perform speed, reduce :
G94: perform speed(F mm/min) =spindle rotate rate(S RPM) *
pitch(P mm/rev)
G95: perform speed(F mm/rev) = pitch(P mm/rev)
G84: when performing, perform speed(F) spindle rotate rate(S),
they are not controlled by turning switch(fix 100%)
