Related parameters and notice: 
1)  If e is 0, the system doesn’t have axial tool retreating action. 
2)  The system alarms if Z/W isn’t specified or the movement is 0. 
3)  The system alarms if X/U is specified but P(Δi) is larger than X axis movement (U/2). If 
P(Δi) is specified to 0, it can be used for axial cycle drilling. 
4)  If Δk is 0 or larger than entire groove depth (W), the system reports error. 
5)  If Δd is 0, the tool isn’t retreated in radial direction; if Δd is larger than Δi, the system 
reports error.
