Five-axis helical interpolation
The "Five-axis helical interpolation" function requires
The five-axis helical interpolation enables two more axes to be programmed.
On programming, a fixed sequence within the block must be adhered to:
1. Circle information including
– type of interpolation (G02/G03)
– the circular axes,
– the interpolation parameter or circle radius.
2. Linear information including
1 to 3 axes to be traversed in linear direction.
