G748 4-axis surface machining

G748 4-axis surface machining (S4045P and Export versions) or 4/5-axis (S3045P, S4060D and S4045P) with rotary tables or tilting tables (dynamic TCPM)

Programming

G748 [A] [B] [C] [D0=...] [X...] [Y...] [Z...]

Parameters

ParameterDescription
A, B, Caxis name.
D0=selects the operating mode:
D0=1 the table always rotates about the tool tip.
D0=0 (default) the table rotates about the point where the tool tip was when the G748 was programmed. This point can be moved by programming the X…, Y…, Z… offset values. For a correct use of G748, the axis of rotation of the tables must be defined by performing the TABLEZEROSETTING procedure.

Enabled: until a G740 is programmed.

G749 4-axis surface machining

G749 4-axis surface machining (S4045P and Export versions) or 4/5 axis (S3045P, S4060D and S4045P) with 1/2-axis rotary heads (dynamic TCPM)

Programming

G749 [A] [B] [C] [I...] [J...] [Q...] [K...] [D0=1] [D1=...]

Parameters

ParameterDescription
A, Brotary axis name.
I,J,Qpositive or negative offset values for the point of rotation. Failing these parameters, the rotation occurs about the tool tip.
Kfor heads with opposing spindles:
K0 first spindle.
K1 second spindle.
D0=1all calculations are referred to head zero position, irrespective of the head position when G749 is programmed. With D0=1, cycle restart and block search are possible. For a correct use of G749, the head zero position must be defined by performing the HEAD ZERO SETTING procedure.
D1=head number (from 1 to 8). By default: D1=1.

Enabled: until a G740 is programmed.
