1. control system advantages:

1) KCUT adopts graph drive technology, generate cutting track automatically with simple setting, reduce time of programming, increase manufacturing efficiency, reduce possibility of mistakes by operator, and save producing cost.
2) Operation is easy, and easy to learn.
3) multiple axes simultaneous control to simplify programming of complicated taper cutting task.
4) Fully support complete servo control, to satisfy trend of market of high accuracy cutting.
5) Internet communication available, swift, and stable. 4G module is available to connect internet, sim card is required
6) Real-time monitoring, ERP system.
7) PLC control, no more PCBs are used, simplified wiring system, less malfunction. And PLC is very power and has good scalability
8) Real-time IO monitoring
9) Standard network cable connection, fast, stable, and efficient

Main functions of KCUT-Kingred CNC wire cut EDM control system

1) It supports graph-based automatic programming, operator does not need to know programming codes, in practical operation, operator needs to load DXF file created by other software then postprocess in KCUT to create cutting track according to instructions in software.
2) Multiple machining modes, flexible for different purposes, for example, single segment cutting, continuous cutting, forward cutting and backward cutting.  
3)XYUVZ can realize 5-axis simultaneous control, drive type could be stepping drive or servo drive, all 5 axes can be monitored in real-time in main interface of cutting.  
4) KCUT shows present machining position, coordinate, finished percent of task and left time to go in real-time. Operator can judge actual cutting status according information in GUI, which could be zoomed according to operator.   
5) Standard taper control system to realize cutting of equal-degrees taper, variable-degrees taper and abnormity (up-down different profile taper). Multiple axes simultaneous control makes complicated taper cutting much easier and efficient.  
6) Standard with multiple cuts capacity to get better surface finish and cut accuracy.
7) With capacity of corner clearing to improve performance of corner cutting.
8) Support compensation of screw pitch, capable of segmental compensation of pitch error of the machine.
9) With automatic alarm function, when machining is done or malfunction appears (such as short circuit), dialogue of alarm pops out and KCUT records information of alarm automatically.
10) Remote control for motion of machine, wire feed, pump, HF power etc., which makes operation more efficient.  
11) Remote has tool setting function (wire straightness setting) to simplify straightness of wire to workpiece, easy to switch parameters for tool setting.
12) Power off recovery function, repositioning start point, pause point, end point, moving track selection function.
13) Cutting program setting includes jump holes setting, mirror, rotation, lead-in line setting and so on.
14) Short circuit detection & feed-back, short circuit alarm. When short circuit happens, wire would move back and feed forward again to get suitable gap between wire and workpiece.
15) Manual function includes move axis, centering, touch edge etc.
16) Setting includes factory default setting, user setting. Factory default setting is not allowed to change unless permission and guidance from manufacturer.
17) IO monitoring could keep monitoring data of input and output and to enable operator know control system better.
18) Debugging system record information of alarms.
19) File management could do setting of graphs in system, it also can read files from hard driver or USB memory, file should be DXF.
20) length measure function to check distance between two points, to make sure graph is correct.
21) Simulation function simulates actual procedure of cutting, to check if programming is correct.
