Computerized Programmable Automation Controller (CPAC) Solution in Metal Cutting Process

Introduction to CPAC

Computerized Programmable Automation Controller (CPAC) developed by Googol Technology is a highly integrated development platform specialized for machine control system and factory automation. It consists of both hardware and software portions. The hardware part includes industrial PC, multi-axis motion controller, PLC, on-site networks and HMI technology. The software part includes a powerful program development tool named OtoStudio which is IEC61131-3 compatible programming environment with many extra functions.

System Overview

Flying shear, rolling shear and flying saw control system are important types of equipment for synchronized shearing of stripes, plates and pipes. They are widely used in processing of steel, aluminum and carton paper.

System Principle

The main function block of flying shear, rolling shear and flying saw control system are briefly explained as follows:

• Cycling function block: To manage the production process, including jogging, homing and rest of shearing axis, processing of production activation, acceleration, deceleration, stop and other operating signals.

• Synchronized shearing function block: Planning of shearing axis motions according to production requirements and encoder feedbacks.

• Exception handling function block: Handling of alarms in production process, motion error and encoder exception to ensure the safety of the machine.

System Configuration

• Controller: CPAC-OtoBox-UCT2-4PV

• HMI: ACC6-PN5-T12-K8

• OtoStudio - Software development platform of the flying shear control system.

• Servo mechanism: HP AC servo drive + HP permanent magnet synchronized AC servo motor

System Evaluation

Synchronized following among different axes is fulfilled precisely via Googoltech's high performance motion controller. Reasonable motion planning curves ensure that synchronized following of acceleration, deceleration and high speed production process between shears and speed of production line, precision is thus raised and smooth cuts result. Friendly human machine interface makes operating convenient. The maximum shearing speed of the system can reach 300m/min. (shearing error <±0.3mm). This proves that Googoltech's CPAC shearing system possesses high performance and reliability.
