19.10 Selecting the rotary axes that position the tool in type-52
kinematics.
The instruction #SELECT ORI may be used to choose onto which rotary axes of the
kinematics the tool orientation is calculated for a given direction on the work piece (part).
Kinematics 52 has at the most 2 rotary axes on the spindle and two rotary axes on the table,
which means that there may be up to 4 rotary axes to orient the tool on the work piece.
Therefore, there are always several solutions when calculating the position of the rotary axes
to orient the tool. The tool orientation on the work piece is calculated in the following
instructions:
Programming.
When defining this instruction, you must define the rotary axes involved in the position
calculation.
Programming format.
The programming format is the following; the list of arguments appears between curly
brackets.
#SELECT ORI [{ROT1}, {ROT2}]
Both arguments are defined using the following commands; HEAD1 (first axis of the spindle),
HEAD2 (second axis of the spindle), TABLE1 (first axis of the table), TABLE2 (second axis
of the table). Any programming sequence (order) is permitted.
Considerations.
This instruction is modal. On power-up, after an M02 or M30 and after an EMERGENCY or
a RESET, the instruction assumes its default value; #SELECT ORI [HEAD1, HEAD2].
• #CS. Define and select the machining coordinate system (Inclined plane).
• #ACS. Define and select the fixture coordinate system.
• #TOOL ORI. Orient the tool perpendicular to the work plane.
• #CSROT. Tool orientation in the part coordinate system.
{ROT1}
Rotary axis of the kinematics.
{ROT2}
Rotary axis of the kinematics.
#SELECT ORI [HEAD1, HEAD2]
Default value.
The tool orientation instructions work on the first and second axes of the spindle,
leaving the table axis in their current position.
#SELECT ORI [HEAD1, TABLE1]
The tool orientation instructions work on the first axis of the spindle and the first axis
of the table, leaving the other two rotary axes of the kinematics in their current
position.
#SELECT ORI [HEAD2, TABLE1]
The tool orientation instructions work on the second axis of the spindle and the first
axis of the table, leaving the other two rotary axes of the kinematics in their current
position.
