High-speed peck tapping cycle: along the X-axis and Y-axis after positioning, rapid traverse to point R, from
R point in each infeed depth Q execution knife cutting, then the tool is retracted distance d (parameter 0608), the
fallback speed 0607 set by the parameter. From d point to continue cutting feed when it reaches point Z, the
spindle is stopped, then rotated in opposite directions and back.
Standard peck tapping cycle: along the X-axis and Y-axis after positioning, rapid traverse to point R, from R
point in each infeed depth Q execution knife cutting, and then fall back to R point, fallback speed set by the
parameter 0607 . From the R point moves (this speed and return speed identical) to the position apart from the last
cutting end d (parameter NO.0608), is the position of cutting restart. When you reach the point Z, the spindle is
stopped, then rotated in opposite directions and back.
WARNING:
During tapping cycle, adjust the feed ban override and spindle override, prohibit the use of feed hold button.
