cycle:
Tool infeeds from starting point in radial direction, retracts, infeeds again, and again and
again, and last tool retracts in axial direction, and retracts to position in radial direction,
which is called one radial cutting cycle; tool infeeds in axial direction and execute the next
radial cutting cycle; cut to end point of cutting, and then return to starting point (starting
point and end point are the same one in G75), which is called one radial grooving
compound cycle. Directions of axial tool infeed and radial tool infeed are defined by
relative position between end point X(U) Z(W) and starting point of cutting. G75 is used for
machining radial loop groove or column surface by radial discontinuously cutting, breaking
stock and stock removal.
Relevant definitions:
Starting point of radial cutting cycle: Starting position of axial tool infeed for each radial
cutting
cycle, defined by An(n=1, 2, 3……), X coordinate of An is the same that of starting point A,
the different value of X coordinate between An and An-1 is Δk. The starting point
A1 of the first radial cutting cycle is the same as the starting point A, and Z starting point
(Af ) of the last axial cutting cycle is the same that of cutting end point.
End point of radial tool infeed: Starting position of radial tool infeed for each radial
cutting cycle, defined by Bn (n=1, 2, 3……), X coordinates of Bn is the same that of cutting
end point, Z coordinates of Bn is the same that of An, and the end point (Bf ) of the last
radial tool infeed is the same that of cutting end point.
End point of axial tool retraction: End position of axial tool infeed (travel of tool infeed is
Δd) after each axial cutting cycle reaches the end point of axial tool infeed, defining with
Cn(n=1,2,3……), X coordinate of
Cn is the same that of cutting end point, and the different
value of Z coordinate between Cn and An is Δd;
End point of radial cutting cycle: End position of radial tool retraction from the end point
of axial tool retraction, defined by Dn(n=1, 2, 3……), X coordinate of Dn is the same that of
starting point, Z coordinates of Dn is the same that of Cn (the different value of Z coordinate
between it and An is Δd);
Cutting end point: It is defined by X(U) Z(W) , and is defined with Bf of the last radial
tool infeed. R(e) : It is the tool retraction clearance after each radial(X) tool infeed, its
range is 0~99.999 (unit:mm, radius value) without sign symbols. The specified value is
reserved validly after R(e) is executed and the data is switched and saved to No.056.
NO.056 value is regarded as the tool retraction clearance when R(e) is not input.
X: X absolute coordinate value of cutting end point Bf (unit: mm).
U: Different value of X absolute coordinate between cutting end point Bf and starting point.
Z: Z absolute coordinate value of cutting end point Bf (unit:mm).
W: Different value of Z absolute coordinate between cutting end point Bf and starting point
A(unit:mm).
P(Δi) : Radial(X) discontinuous tool infeed of each axial cutting cycle, its range: 0＜Δi≤
9999999(IS_B)/ 0＜Δk≤ 99999999（IS_C） (unit: least input increment, without sign
symbol).
Q(Δk) : Axial(Z) discontinuous tool infeed of each radial cutting cycle, its range: 0＜Δk≤
