Processing details
• Performs normal line control for an axis selecting a plane. (G17: Plane X-Y axis, G18: Plane Z-X axis, G19: Plane Y-Z axis)
Center of rotation
Tool end
• The G42.1 command is modal. Normal line control continues until normal line control cancel (G40.1) is commanded.
• Set the axis name of the axis for normal line control in [Motion Control Parameter][G-code Control Parameter][G-code
Control System Parameter]"Normal Line Control""Normal Line Control Axis". When a normal line control axis is set to
"0: No Normal Line Control" and G42.1 command is executed, a minor error (error code: 1FC3H (details code: 031BH))
occurs, and normal line control is not performed.
• There are two types of rotation methods for a normal line control axis. They are normal line control type , and normal line
control type . Set the normal line control type in [Motion Control Parameter][G-code Control Parameter][G-code
Control System Parameter]"Normal Line Control""Normal Line Control Type".
• Refer to normal line control function for details of normal line control. (Page 211 Normal Line Control Function)
