Ap, Bp : Angular displacement of the rotation axis
Movement amount of linear axis
Xp=L× [cos(B+Bp)-cos(B)]
Yp=L× [sin(B+Bp)×sin(A+Ap)-sin(B)×sin(A)]
Zp=-L× [sin(B+Bp)×cos(A+Ap)-sin(B)×cos(A)]
Angular displacement of the rotation axis
Ap=Hp or Bp=Hp
Changing tool length compensation in the longitudinal direction of the tool
Select the mode of changing the tool length compensation in the
longitudinal direction of tool when both the following modes are
selected: Mode of tool length compensation in the longitudinal
direction of the tool (G43.1) and mode of manual handle interrupt
(MOVL and H are on). Then rotate the handle of the manual pulse
generator. The tool length compensation is changed in the longitudinal
direction of the tool.
The change is cleared to zero when a reset or the G49 command is
executed or when the offset number is changed.
Tool axis direction tool length compensation value modification mode
is enabled when the following five conditions are satisfied:
(1) Manual handle interrupt mode is selected.
(2) Tool axis direction tool length compensation mode (G43.1) is set.
(3) Tool axis direction tool length compensation mode (G43.1) is set.
(4) In parameter No. 7556, the axis number of the first manual pulse
generator is set as the axis for tool axis direction tool length
compensation value modification mode.
(5) A manual handle feed axis is selected for the axis number set in
parameter No. 7556.
