Abstract
Background:
WEDM (Wire Electrical Discharge Machining) is widely used to machine
difficult-to-machine materials, such as high-strength and high-brittle materials. The research on tension
control device of the wire electrode is mainly to improve the machining precision and surface quality of
WEDM.
Objective:
To meet the growing demand for processing of difficult-to-machine materials, such as highstrength
and high-brittle materials, the machining precision and surface quality of WEDM are improved
continuously.
Methods:
This paper reviews various representative patents related to the tension control device of wire
electrode in WEDM.
Results:
Through retracing the characteristics of different types of the tension control device of wire
electrode in WEDM, the main problems existing in the current development are concluded and analyzed.
The development trend of patents on the tension control device of wire electrode in WEDM is
discussed.
Conclusion:
The optimization and development of the tension control device of wire electrode in
WEDM are beneficial to improve the machining precision and surface quality of WEDM. More related
patents on the tension control device of wire electrode in WEDM will be invented.
