CHAPTER 1 INTRODUCTION
The ELEKTRA Wire cut electrical discharge machine comprises of Machine Tool, a power supply Unit (ELPULS), and a Dielectric unit and a chiller unit. The machine tool unit comprises of a main worktable (fixed type) on which the workpiece is clamped, a moving column on X & Y axes, wire drive mechanism and auxiliary axes U & V & Z are mounted on the moving column. The X and Y axes are moved in steps of 1 micrometer by means of D.C. servo motor. The U& V axes which parallel to X & Y axes respectively are driven by the same motors which drives the table. The traveling wire which is continuously fed from wire feed spool which moves through the workpiece and is supported under tension between a pair of wire guides which are located at the opposite sides of the workpiece. The lower wire guide is stationary whereas the upper wire guide which is supported by the U-V table can be displaced transversely, along U and V axes, with respect to the lower wire guide. The upper wire guide can also be positioned along Z axis by moving the quill. A series of electrical pulses generated by the pulse generator unit are applied between the workpiece and the traveling wire electrode, to cause the erosion of the workpiece material. As the material removal or 24-C
machining proceeds, the worktable carrying the workpiece is displaced transversely by the X-Y controller and the driver along a predetermined path programmed in the controller. The path specifications can be supplied to the controller via a program which is stored on floppy disk or directly the controller (MDI made) When the X-Y table is moving along the predetermined path, if the U-V table is kept stationary, a straight cut with a predetermined pattern is formed. In order to produce taper machining, the wire electrode has to be tilted. This is achieved by displacing the upper wire guide (along U-V axes) with respect to the lower wire guide. The desired taper angle is achieved by simultaneous control of the movement of X-Y axes and U-V axes with their respective predetermined paths stored in the controller. The path information of X Y table and U-V table is supplied to the controller in terms of linear and circular elements via floppy disks. While the machining is continued, the machine zone is continuously flushed with water passing through the nozzles on the both sides of the workpiece. Since water is used as a dielectric medium, it is very important that water does not ionize. Therefore to prevent the ionization of water an ion exchange resign is used in the dielectric distribution system to maintain the conductivity of the water constant. The part programming system comprising of an 24-C
ASCII keyboard, CRT with a fine resolution graphics features, double sided double density floppy disk drive. The geometry of the profile and the motion of the wire electrode tool along the profile is fed to the part programming system through keyboard, in terms of various definitions of points, lines and circles as the tool path element, in a totally menu driven, conversational mode. The wire compensation (for wire diameter and machining over-cut) and taper gradient can be specified for the total path or for each element separately. After the profile is fed to the computer, all the numerical information about the path is calculated automatically and it's printout can be generated if required. The entered profile definition, the profile is recorded by the computer on the floppy disk which is then removed and put in the controller for execution of the program.

FOUNDATION DETAILS (Ref. Fig.5) The machine should be kept on a rigid foundation. Foundations confirming to the standard machine tool requirements should prove adequate. A flat hard concrete floor at least 200 mm thick is recommended in the area where machine is to be installed. Do not use separate concrete blocks as foundation under the leveling pads of the machine. If the place of installation does not have industrial flooring and if there are many machines inducing vibrations, isolated foundation flooring is recommended. INSTALLATION OF MACHINE TOOL 1. Installation work of machine tool is an important factor which affects accuracy of the job done, machine tool life and maintenance. So it should be done carefully and systematically. 2. Remove the transport locks (Ref. Fig. 2, 3). The machine tool is to be placed on five leveling pads. Install these leveling pads in their places before the machine is placed. 3. The level of the floor should be sufficiently horizontal as the range of adjustment of pads is limited. Level the machine in both x & y directions with the help of precision level (sensitivity = 0.02 mm /1 m) .See to it that all the axes be at the center while checking the level. The reading should be within half division. 4. After leveling the machine see to it that lock-nuts are tightened so that the level is not disturbed. 5. All the 3 units viz. The machine tool, the power supply unit & the Pump filter unit should be located as per the floor plan given. Leave a distance of 500 mm between unit & wall. This will prove useful at the time of maintenance. 6. Make all the connections of the generator with the machine tool. See whether all cables are intact. 24-C
7. Make all the connections of the generator with the machine tool. 8. Fill distilled water in P.F. unit, put filters and resin and check the connections of all the 3 phase motor & see that all interconnecting pipes are tightened properly. 9. Check the supply from the stabilizer. Check voltage between neutral & earth, it should be less than 1 volt. Check direction of motor rotation & valve fitting. 10.Make wire verticality with the help of verticality block, before making wire vertical dial the block within 2 microns w. r. t. Z axis. 11.Load some job and start sparking. LEVELING PROCEDURE
1) When the m/c tool is being placed on the floor ensure that the gap between the floor and m/c base is 110 mm to 115 mm, it must not be less than 110 mm. Gap can be adjusted by adjusting the leveling bolts on the m/c tool base. The gap of 100 to 115 mm is to be maintained to avoid the obstruction of drain pipe with the PF unit and proper alignment of wire collection box. 2) After the m/c tool is placed on the floor as per the floor plan in the E and C readiness check list, clean all the ground surfaces provided on the m/c base. 3) There are 8 leveling bolts on m/c base. Lift the bolts no. 2, 4, 5 and 7 and ensure that the bolts no. 1, 3, 6 and 8 are touching the floor. 4) Keep all the axes at the middle position of total stroke. Take the spirit level of accuracy 0.020/meter. • Keep the spirit level on surface marked “A” in diagonal direction as shown in fig and note the results. • Keep the spirit level on surface marked “B”, note the result. • Depending on the results of above checks, adjust the leveling bolts no. 1 and 3 such that the level of m/c is within 4-5 divisions. • Place the spirit level on the surface marked “C” and “D” and ensure 24-C
that the level of the m/c is within 4-5 divisions. If not, adjust the bolts no. 6 and 8. • Place the spirit level on the surface marked “A” in vertical and horizontal direction and level the m/c within 3 divisions by adjusting the bolts no.6 and 3 respectively. • Similarly place the spirit level on the surface marked “B”, “C” and “D” and level the m/c within 3 division of the spirit level by adjusting the leveling bolts 5) After leveling the m/c, adjust the leveling bolts no.2, 4, 5 and 7 such that the leveling pads touch the floor and then tighten all the leveling bolts and lock them by nut on the bolt. After this check once again the level of the m/c is not disturbed and is within 3 divisions of the spirit level. Please note that the leveling should be done by keeping the spirit level on the ground surface provided on the base and not by keeping the spirit level on the job stand, it may create inaccuracy in the squareness of the X and Y axis.

PREPARATION FOR MACHINING 1. Selection of wire :-
Use brass wire specified by M/s. Electronica, Pune, INDIA. It must be free from any twists, corrosion and kinks, any of these defects may lead to wire breakage or unstable machining. 2. Wire threading :- (MANUAL)
Wire threading is to be done as per the procedure given below a) Mount the wire reel on its shaft so as to unspool the wire in the direction as shown in the figure. Tighten the nut firmly in a clockwise on to the reel. b) Wound the wire over the rollers as shown and then thread the wire through the wire guides, over the carbide current pick up and through the pallet of the flushing assemblies. c)
The wire should pass through the groove centers of the wire guides. Confirm that the wire is positioned at the center of the dielectric fluid flushing port in order to the wire surrounding completely by the water
column.
d) The wire must remain in contact with the nylon roller at all times so that it is insulated from the machine tool. e) Do not touch the wire or any part of the wire feed mechanism, 24-C
during machining since all are electrically live.
3. Wire tension and wire feed rate
The wire tension is to be adjusted according to the workpiece thickness and size of wire used. Proper tension is set by adjusting the knob of wire tension. The wire feed is to be adjusted on the basis of thickness of the job and energy settings.
4. Automatic Wire Threading :
The machine has optional automatic wire threading attachment (AWT). For threading of wire with AWT the wire should be of hard type. Insertion of wire up to AWT is manual. Hence while changing the wire spool first insertion of wire is manual. Refer to chapter no. 6 for more details on wire drive with Automatic wire threading system.
FLUSHING AT LOW & HIGH FLUSHING
The interfacing of machine tool with pump filter unit is done by connecting the two hoses coming from flow meters to the distributor block .The drain pipe that is fixed to the tank emerges into the tank of filtration unit between the cutout of the tank. By adjusting the knob of the flow meters pressure of water coming out of the flushing assemblies can be adjusted. For high speed cutting, flushing at high pressure is selected. The pressure / flow selection is also programmable. To carry on the cutting at lower speed or while taking the second cut on the job already usually low flushing pressure is selected. 24-C
Dielectric fluid flushing parameters
Confirm that conductivity of the dielectric fluid is within the specified the specified range. Press the flush switch on the control box. Adjust dielectric fluid flow valve by watching the flushing pressure fluid flowing from the upper & lower flushing pressure should be approximately 12 kg / cm ². The function of the deioniser is to reduce the conductivity of dielectric fluid through the ion exchange reaction of resin. CONDUCTIVITY CORRECTION
When the conductivity goes too low or too high than the set values' Conductivity control unit ` following corrective measures should be taken.
EVENT ACTION Conductivity higher than the set Add distilled water or change the higher value. resin in deionizer if the resin is tending to become inactive.
Conductivity lower than the set Add tap water. lower value.
