What type of controller used within CNC Lathe?
what type of controoer used in CNC Lathe? PD, PI or PID Control?
Answers:
*PID WITH SOME IMPROVEMENT.
*A proportional-integral-derivative controller (PID controller) is a generic control loop feedback mechanism widely used surrounded by industrial control systems. A PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective feat that can adjust the process accordingly.
The PID controller calculation (algorithm) involves three separate parameter; the Proportional, the Integral and Derivative values. The Proportional value determines the reaction to the current error, the Integral determines the spontaneous effect based on the sum of recent errors and the Derivative determines the reaction to the rate at which the error have been changing. The weighted sum of these three whereabouts is outputted to a control element such as the position of a control valve or power into a heat element.
By "tuning" the three constants in the PID controller algorithm the PID can provide control feat designed for specific process requirements. The response of the controller can be described in terms of the responsiveness of the controller to an error, the point to which the controller overshoots the setpoint and the degree of system oscillation. Note that the use of the PID algorithm for control does not guarantee optimal control of the system.

most all controllers use some sort of PID control for positioning to control speed and position. Allen Bradley, FANUC, etc controllers can be used wiht the proper inputs and outputs.
