CE MILLING (Cy

Feed rate for milling

Q207: Traversing speed of the

tool in mm/min during milling. Input range 0 to
99999.9999; alternatively FAUTO, FU, FZ

Feed rate for finishing

Q385: Traversing speed of

the tool in mm/min while milling the last infeed. Input
range 0 to 99999.9999; alternatively FAUTO, FU, FZ

Feed rate for pre-positioning

Q253: Traversing

speed of the tool in mm/min when approaching the
starting position and when moving to the next pass.
If you are moving the tool transversely to the material
(Q389=1), the TNC moves the tool at the feed rate for
milling Q207. Input range 0 to 99999.9999;
alternatively FMAX, FAUTO, PREDEF

Set-up clearance

Q200 (incremental): Distance

between tool tip and the starting position in the tool
axis. If you are milling with machining strategy
Q389=2, the TNC moves the tool at the set-up
clearance over the current plunging depth to the
starting point of the next pass. Input range 0 to
99999.9999; alternatively PREDEF

Clearance to side

Q357 (incremental): Safety

clearance to the side of the workpiece when the tool
approaches the first plunging depth, and distance at
which the stepover occurs if the machining strategy
Q389=0 or Q389=2 is used. Input range 0 to
99999.9999

2nd set-up clearance

Q204 (incremental): Coordinate

in the spindle axis at which no collision between tool
and workpiece (fixtures) can occur. Input range 0 to
99999.9999; alternatively PREDEF
