Operation of Digital Conductivity Meter 1. Normally, 5 seconds after machine power turned on, PV will be lit on, which indicates the digital conductivity meter is displaying correct value and in stand-by status. 2. Next, press SV button, the screen will display previous target value, which can be readjusted by UP and DOWN button. 3. When new setup is done, press SV button to save it into memory; if not save the value, the value may as same as previous value and then return to PV mode after a few seconds. 4. Once the new target value is set higher than current one, deionization process (Working lit on) will start until new target value reached; however, if new target value is smaller than current one, water conductivity will remain the same until ion-resin completely consumed or diluted by new tap water. 4. When water level is too low, WATER LOW alarm will be lit on and blocks deionization process temporarily until alarm dissolved. 5. The latest status of Digital meter before system shut down will be memorized. Note (1). Cleaning of probe. It is recommend clean the probe once every month to maintain the accuracy of measurement. (2). Push PV button to exit SV mode any time. (3). To avoid de-ionization over frequently, the activation will be put off for a default period. 2. Flush water regulation (1).

8. Comp. Corner Ratio：To set the distance off the program path in Corner Control. The distance equals Offset (H or D) x Comp. Corner Ratio. Distance off program path

9. Taper Set 1. Cut Modes： 0= Vertical：Aux plane remains vertical to PGM plane, which means there is no UV axis movement. 1=Taper：Aux plane is oblique to PGM plane at a specific degree of angle. In this case, XYUV axis would be moving simultaneously in identical path to cut cone shape. 2=UV：XYUV axis would be moving simultaneously but in different path to cut two shapes on the top and at the bottom of a workpiece. 3=Plane：Same as 2=UV used for cutting two shapes on top and at bottom but in different way of program composition. The program of 2=UV, in which the shape on top is consisted of innumerable points and lines while 3=Plane can use G, M code to compose it to much simplified the program and enhance the accuracy.

10. Taper angle：When performing a taper cutting and if taper angle is not defined in the NC program, the value of the taper angle can be set by this value also. 11. NC PGM Plane (Z)：Generally, Z (PGM Plane) is the distance off work-table in a N.C. program; usually set Z=0 if there is no spacer put beneath a work-piece. 12. Object Thick (I)：I (Aux Plane) is referred to the height position of the work-piece; its value could be + or – and it is used to exchange the position of PGM and Aux plane. For example, in above Cut Mode=3, it is set Z=0 and I=30, so UV path appears on top. If we set Z=30, I=-30, then the path will be turned up-side down.

Note 1: How to make Taper Cutting? Answer: There are two variables, Z and I, are related to the setup of Taper Cutting; the figure below shows how they are correlated to：

I

Z

Z (PROGRAM PLANE) is the base line of taper, and I (THICKNESS) is the height of taper, which could be set as “+” or “—” and will create different taper shape. See figure below： +I

① CORNER DATA : We discuss「Inner Corner」,「Exterior Corner」separately.

1. Ctrl-SW: Open / Close corner control (0=Off, 1=On.) 2. Corner Type: Corner control method 0~5, total 6 types. (Now mode 1、3 、 4、5 are reserved). The rest mode 0& 1, we would introduce the difference as under: a. Type 0：Power of spark energy control. (increase or decrease) ex: Suppose the S.CODE ：ON =5, OFF=9, AN=3, AFF=9 if set the「PWR.R」 =0.5，then means the power would be reduced 50%, for instead, the S.CODE would has changed to ON =2, OFF=18, AN=1; AFF=18. b. Type 2：Max. Feed-rate override control. (increase or decrease) ex: Suppose the S.CODE ：ON =5, OFF=9, AN=3, AFF=9 ; now current speed is 100mm2/min and if set the「MAX.FEED」 =75，then means the federate speed would be reduced 25%, for instead, the all S.CODE would has changed and driven by controller. (Majority to change OFF、AFF、 SV、FR) Note: For skim cut,「CUT NO. vs. Max. Feed」is also be activated while the type 2 is set. 3. Enter Pwr. R. ： Reduction percentage of original eroding energy when approaching the corner (Enter Dist.) The range set from 0.2~1.0. 「1.0」means no any deduction of the spark energy. 「0.8」means for corner control 20% spark energy would be reduced accordingly. (ON、OFF、AN、AFF) Ex: If ON =6, OFF= 9, AN=4, AFF=9 ; if set the「Enter PWR.R」 =0.8， then means the power would be reduced 20%, for instead, the S.CODE would has changed to ON =4, OFF=11, AN=3; AFF=11. 4. Exit Pwr R.：Similar to point#3 mentioned, the different is to the exiting power energy reduction after the corner is passed. 5. Enter Dist.：Approach distance of Corner Control. Set unit from 0.01~20mm. 6. Exit Dist.：Exit distance of Corner Control Set unit from 0.01~20mm. 7. Radius：Set what Corner radius to activate Corner Control. For example, if Radius=0.5, Corner Control would be activated for all the R≦0.5mm arc path in N.C. program.. 2-70

CHMER Wire-Cut EDM Operation Manual W5F

8. Dwell：Pause time after Enter Dist. It is recommended to use Dwell for clean cut on inner angle. Set unit is from 0 ~30 sec. 9. Max Feed：Limit the maximum cutting speed of Corner Control (mm2 / min) Set unit is from 10~2000mm2. 10. Inc. OV (-4~4)：OV increase in Corner Control. 11. Inc. ON (-4~0)：ON decrease in Corner Control. 12. Inc. OFF (0~40)：OFF increase in Corner Control. 13. Inc. SV (-40~40): SV increase in Corner Control. Note: There SV is no active for exterior corner during 1 or 2 skims cut ; However, SV setting is always be effected to inner corner even during 1 or 2 skims cut. 14. Inc. FR (-40~40): FR decrease in Corner Control. 15. Inc. WT (0~4): WT increase in Corner Control. 16. Inc. WL (-4~0): WL increase in Corner Control. 17. Scode Base(0~999): To use a set S-code as basement for changing. (Reserved) 18. REG. DAT. BAS: A register to save the present corner data to corner database. 19. CALL: Accroding input conditions and recall the corner data from database. a.Wire Dia. Dia 0.1 mm ~0.3mm b.Material: 0 =Default, 1= SKD-11, 2 =COPPER, 3=WC, 4=AL, 5= GRAPHITE, 6=SKD-61, 7=TITANIUM, 8= P20 c. Thickness: Input job thickness. The set unit is from 0.001~500. 20. CUT NO. vs. Max. Feed: The power [Methematics] to change the Max. Feed-rate override control for skims cut. (No. 2~ 6) Ex: If F=2.0mm/min, 1 skim = 1.5 and therefore the corner feed-rate is 3.0mm/min. (1cut speed X 1 skim cut value)

Appendix ： Ethernet Setup（ETHRRNET SET） The construction of Ethernet Network is through a physical switching HUB there are the cables connected between server (User’s PC) and client (CHMER controller); CHMER provide the Ethernet connector be ready on our controller (GIPC .NET board) and attach full authorized software supported. Refer the figure as follow:

Note：Repeatedly to check the work lamp LED status whether lit on mother board (controller) & switching HUB. It’s quite important ! Otherwise, the setup of local LAN becomes meaningless, before the software operation must confirm this point in advance. There, step by step we would utter the setup procedures into three parts separately: 1. Setup of PC or Laptop（server; user computer） 2.Configure the content of the batch file AUTOEXEC.BAT & boots memory load file CONFIG.SYS 3. Setup of Controller software（client; controller)）

Connection Example：[Machine controller as server end, PC as client end] STEP1：(PC) Mouse cursor select 「START」  「EXECUTION」input command 「cmd」 ， entry to virtual DOS，input command 「ipconfig」 ，then user can acquire the information：1. Machine IP Address 2. Sub Mask IP 3.
