Rotation Area Interference Check
Rectangles to make up interference check group A
In the state in which the B-axis is positioned at the reference rotation angle
and a reference position return is performed on the X- and Z-axes, set the
rectangles to make up interference check group A.
Interference check group A is represented by three rectangles below.
＝

Rectangle 2 Rectangle 1
Rectangle 3
Interference check group A
Taking rectangle 1 as an example, "measure the distances from the machine
zero point" to the maximum and minimum points of rectangle 1.
Maximum point

Parameter No. 14920 = Rectangle 1 1st axis maximum point distance
Parameter No. 14921 = Rectangle 1 1st axis minimum point distance
Parameter No. 14922 = Rectangle 1 2nd axis maximum point distance

  • Page 7NOTE 1 It is not possible to cause the alarm to be generated before interference check groups interfere with each other. It is, therefore, necessary to define areas with sufficient margins according to the feedrate. The distance to move along the axis after the alarm is generated can be determined w
