they are not going to be replaced

Outdated cutter compensation and acceleration algorithms can cause inaccurate parts, gouging, and overshooting leading to an increase in scrap parts. Many CNC controls are available for retrofit, but that doesn't mean they have the same features as the old control. The features may not work the same way and/or existing programs may not be compatible. When deciding to replace a CNC control, compatibility with the existing part programs, Vertical Lathe, motors, and feedback devices must be considered, as well as consistency in the operation of the control Compatibility with the drives, motors, and feedback devices is definitely an issue if they are not going to be replaced. If the new control doesn't support features in the existing part programs, or if the features work in a different way with the new control, substantial editing or reprogramming of the existing part programs may be required. In a situation where hundreds of programs or even a few very long programs are regularly run on the machine tool, existing programs must be compatible with the new control or substantial time must be invested rewriting, converting, editing, and proving programs. Another important issue to consider is the amount of time that may be required to retrain operators if the new control operates or looks significantly different. New capabilities that can save time, such as part and tool probing, are another benefit of control retrofitting. For example, the CNC Vertical Lathe includes probing cycles that allow setup and inspection of parts right on the machine. For companies with inspection requirements, this can reduce or eliminate secondary operations on a CMM. The installation of the control is yet another very important consideration when purchasing a retrofit control. Whether installation is implemented in house or by the OEM, it is important that the retrofit kit is designed ahead of time.
