Abstract

The invention described herein generally pertains to a system and method related to integrating cutting or marking operation parameters and motion parameters. A controller is provided that manages both process related control and motion related controls rather than having separate controllers with respective connectivity. The controller provides integrated process related control and motion related control which directly controls a cutting or marking operation with improved dynamics while minimizing connectivity and data communications.

What is claimed is:

1. A system for cutting or marking a workpiece, comprising:
an implement that performs an operation, wherein the operation is at least one of a cutting of the workpiece or a marking of the workpiece;
a gantry;
a table that supports the workpiece;
a power supply;
an input component that is configured to receive a user input associated with a parameter to perform the operation;
a controller that is configured to provide the following:
a height control for the implement that manages a motion toward the workpiece or away from the workpiece;
a consumable control for the operation;
a power control to the power supply for the operation;
a motion control for the implement that manages a motion about the workpiece; and
a process control for a sequencing of at least one of the height control, the consumable control, the power control, and the motion control for the operation.

2. The system of claim 1 , wherein the operation is at least one a laser operation, a waterjet operation, or a milling operation.

3. The system of claim 1 , wherein the operation is a plasma operation.

4. The system of claim 3 , wherein the consumable control for the operation is gas selection and the process control includes a sequencing of at least one of a gas, a current, or a voltage.

5. The system of claim 3 , wherein the process control includes a sequence of the height control and the motion control.

6. The system of claim 3 , further comprising:
the height control is a set of machine readable instructions for a drive that controls a motion in a z axis;
the consumable control is a set of machine readable instructions for at least one of a pressure transducer, a proportional valve, or a solenoid valve related to a gas selection for the operation;
the power control is a set of machine readable instructions for the power supply;
the motion control is a set of machine readable instructions for a drive that controls at least one of a motion in an x axis about the workpiece, a motion in a y axis about the workpiece, a travel speed, a lead in, or a lead out;
the process control includes a set of machine readable instructions for sequencing at least one of a gas used with the operation, a current for the operation, or a voltage of the operation; and
the controller communicates with the drive that controls the motion in the z axis, the drive that controls the motion in an x axis, the drive that controls the motion in a y axis, and at least one of the pressure transducer, the proportional valve, or the solenoid valve related to the gas selection, wherein the controller communicates without an RS422 Comm.

7. The system of claim 1 , wherein the parameter is a desired shape profile for the workpiece or a contour for the workpiece.

8. The system of claim 1 , wherein the parameter is at least one of a thickness of the workpiece, or a material type of the workpiece or a cutting velocity.

9. The system of claim 1 , the input component is further configured to communicate the user input wirelessly to the controller.

10. The system of claim 9 , wherein the input component is incorporated into the power supply.

11. The system of claim 1 , wherein the controller is affixed to the gantry.

12. The system of claim 1 , the controller further includes at least one of the following:
a first communication component that receives data for the controller from at least one of a drive that controls a motion in a z axis, a pressure transducer, a proportional valve, a solenoid valve, a drive that controls a motion in an x axis, a drive that controls motions in a y axis, or the power supply of the operation; or
a second communication component that transmits data from the controller to at least one of a drive that controls a motion in a z axis, a pressure transducer, a proportional valve, a solenoid valve, a drive that controls a motion in an x axis, a drive that controls motions in a y axis, or the power supply of the operation.

13. The system of claim 12 , at least one of the first communication component or the second communication component is at least one of an Ethernet, a serial real time communication system (Sercos), a controller area network (CAN), a network, a LAN, a WLAN, or a wireless network.

14. The system of claim 1 , the controller is further configured to generate an updated machine readable instruction for at least one of the height control, the consumable control, the motion control, the power control, or the process control, wherein the updated machine readable instruction is based on a dynamic monitoring of the operation.

15. A system that performs a plasma cutting or marking operation on a workpiece, comprising:
a gantry;
a torch;
a table that supports the workpiece;
