Calculation of the kinematics dimensions.
9.10.1 Swivel (angular) spindle. Calculation of the dimensions using a probe.
This example calculates the dimensions of a YZ 45º angular spindle, parameter TYPE = 6.
Then next example uses a probe and a sample part secured to the table, with its sides aligned
with the main axes of the machine.
The CNC can have configured two probes. Before any probing move, the CNC must know
which is the active probe, or, which is the same, which of the two probes it must attend to.
It is selected via part-program or MDI using the instruction #SELECT PROBE.
Dimensions to calculate at a YZ angular spindle (TYPE=6).
In this type of kinematics the following dimensions must be defined. All the parameters may
be set with a positive or negative value. The (+) sign in the illustrations indicates that the
direction is assumed as positive.
The machine parameters associated with the probe movement
must be set and the probe must be properly calibrated. You need
to know the length and radius of the probe to calculate the
dimensions of the spindle.

If a probing move is executed without activating the probe, it will not send any signal to the CNC when
it makes contact. This can cause the probe to break because the probing move will not be stopped.
TDATA1 It indicates the distance between the tip of the quill and the secondary
rotary axis along the Z axis.
TDATA2 It indicates the distance between the secondary rotary axis and the main
axis along the X axis.
TDATA3 It indicates the distance between the secondary rotary axis and the main
axis along the Y axis.
TDATA5 It indicates the distance between the tool axis and the secondary rotary
axis along the X axis.
TDATA6 It indicates the distance between the tool axis and the secondary rotary
axis along the Y axis.
TDATA7 It indicates the angle between the main and secondary rotary axes on
rotary spindles (in this case TDATA7 = 45).
