Abstract
A method of operating an electrochemical machining system includes selectively performing an electrochemical machining process by an electrochemical machine of the electrochemical machining system in a macromachining mode or a micromachining mode by controlling a purity level of a machining liquid supplied to the electrochemical machine.
Claims18
A method of operating an electrochemical machining system, comprising:
- selectively performing an electrochemical machining process by an electrochemical machine of the electrochemical machining system in a macromachining mode or a micromachining mode by controlling a purity level of a machining liquid supplied to said electrochemical machine.
A method of operating an electrochemical machining system, comprising:
- directing a used machining liquid from an electrochemical machine to a first container;
- receiving the used machining liquid in the first container;
- supplying a volume of the used machining liquid from the first container to a separation system, wherein the separation system is configured to receive the used machining liquid and deliver a treated machining liquid;
- receiving the treated machining liquid in a second container;
- and
- selectively performing an electrochemical machining process by said electrochemical machine in a macromachining mode or a micromachining mode by controlling supply of a quantity of the used machining liquid from the first container and a quantity of the treated machining liquid from the second container to said electrochemical machine.

A method of operating an electrochemical machining system, comprising:
- selectively performing an electrochemical machining process by an electrochemical machine of said electrochemical machining system in a macromachining mode by applying a first potential to said electrochemical machine or in a micromachining mode by applying a second potential to said electrochemical machine, wherein the first potential is higher than the second potential;
- and
- selectively providing a low purity machining liquid to said electrochemical machine when performing the electrochemical machining process in the macromachining mode or a high purity machining liquid to said electrochemical machine when performing the electrochemical machining process in the micromachining mode.
An electrochemical machining system comprising:
- an electrochemical machine configured to selectively perform an electrochemical machining process in a macromachining mode or a micromachining mode;
- a first container in fluid communication with the electrochemical machine and configured to contain a used machining liquid received from the electrochemical machine;
- a separation system in fluid communication with the first container, wherein the separation system is configured to treat a volume of the used machining liquid received from the first container and deliver a treated machining liquid;
- a second container in fluid communication with the separation system and configured to contain the treated machining liquid received from the separation system;
- and
- a flow controller in fluid communication with the first container and the second container, wherein the flow controller is configured to:
- direct a quantity of the used machining liquid, a quantity of the treated machining liquid or a combination thereof to said electrochemical machine to selectively provide a low purity machining liquid when said electrochemical machine performs the electrochemical machining process in the macromachining mode or a high purity machining liquid when said electrochemical machine performs the electrochemical machining process in the micromachining mode.
