To do this, the system calculates theposition of the circle center point.You can choose to traverse the arc in the clockwise or anticlockwise direction. Depending onthe direction of rotation, there are two options for approaching the target position from thecurrent position via an arc of the specified radius.You can select the arc of your choice by entering a positive or a negative sign for the radius.2SHQLQJDQJOHJUHDWHUWKDQr2SHQLQJDQJOHXSWRr6WDUW7DUJHWFigure 10-19 Opening angleProgramming technology functions (cycles)10.7 Additional cycles and functions in ShopTurnTurningOperating Manual, 05/2017, A5E40868721 579
