6 TURN PLUS 290
Roughing contour-parallel (G830)
Parameters
P:
Cutting depth (maximum infeed)
A: Approach angle (reference: Z axis) – default 0°/180° (parallel
to Z axis)
W: Departing angle (reference: Z-axis) – default 90°/270°
(perpendicular to Z-axis)
X, Z: Cutting limit
Type of oversize is set by soft key
I, K: Different longitudinal/transverse oversize
I: Constant oversize – generates ”oversize G58” before the
cycle
E: Reduced plunging feed rate
Q: Type of retraction at cycle end
■ Q=0: Return to starting point – first X, then Z direction
■ Q=1: Positions before the finished contour
■ Q=2: Lifts off to the safety clearance and stops
Undercutting (see soft-key table)

TURN PLUS generates the working blocks for all roughing operations
(longitudinal, transverse, hollowing, inside, outside, etc.). All the
elements contained in a working block are determined (tools, cutting
data, cycle parameters, etc.).
