B-63782EN/01 NC FUNCTIONS 16.COORDINATE SYSTEM CONVERSION FUNCTION
- 225 -
The coordinates rotation mode is changed by instructing in the above-
mentioned.
By this command, commands thereafter are rotated in the angle
commanded by R, with the point commanded by alpha, beta as the
rotation center.
The least input increment for specifying coordinate system rotation
angles is 0.001 degree or 0.00001 degree. When bit 2 (RTR) of
parameter No. 6400 is set to 0, 0.00001 degree is used; when the bit is
set to 1, 0.001 degree is used.
The rotation plane is the plane selected (G17, G18, G19) when G68
was commanded.
When α_ β_ is not programmed, the tool position when G68 was
programmed is assumed as the center of rotation.
