As such, listed here are considerations before making the decision to automate. 1. Management buy-in. Before spending time investigating the need for automation, it is important for upper management to agree that this is a viable option.
Cnc Machine is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process a program with a control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through an information carrier.
Fig 5.6 Application in Drilling Machine Figure 5.6 shows an application of regenerative circuit in a drilling machine. Here a 3-position, 4-way, regenerative center directional control valve is used. When the DCV is in the spring-centered position, port P is connected to A and B and tank port T is blocked.
