Application : MCS Electronic Universal Testing Machine is designed tor testing metals and other material under tension, compression, bending, transverse and shear loads, Hardness test on metals can also conducted

Principal of Operation : Operation of the machine is by hydraulic transmission of load from the test specimen through pressure transducer to a separately housed load indicator. The system is idea since it replaces transmission of load through levers and knife edges which are prone to wear and damage due to shock on rupture of test pieces
Load is applied by hydrostatics y lubricated ram. Main cylinder pressure is transmitted to the pressure transducer housed in the control panel. The transducer gives the signal to the electronic display unit, corresponding to the load exerted by the main ram. Simultaneously the digits electronic encoder fitted on the straining unit gives the mechanical displacement to the electronic display unit. Both the signa s are processed by the mcroprocessor and load and displacement is dsp ayed on the digits readouts simultaneously.

Machine consists of Straining Unit : This consists of a geared motor with chain & sprocket drive and a table coupled with the ram of the hydraulic cylinder, mounted on to a robust base. The cylinder and the ram are individually apped to eliminate hid on The upper cross-head is rigidly fixed to the table by two strengtaned columns.
The lower cross-head is connected to two columns which are driven by a motor Axia loading of the ram s ensured by relieving the cylinder ram of any provision side loading by the provision of ball seating
An displacement scale with a minimum graduation of 1 mm, is provided to measurethe deformation of the specimen. Tension test is conducted by grpping the test specimen between the upper and lower cross-heads.
Compression transverse, bending shear & hardness tests are conducted between the lower cross-head and the table. The lower cross-head can be raised or lowered rapidly by operating the screwed columns, thus facil rating ease of fixIng or the test specimen. Control Panel :The control pane consists of power pack complete withdr ve motor and an oil tank control valves and electronic display unit.
Power Pack :The Power Pack generates the maximum pressure of 200 kgf/cM. the hydraulic pump provides continuously non-pulsaating oil flow Hence the load application is very smooth.
Hydraulic Controls : Hand operated wheels are used to control the flow to and from the hydraulic cylinder the regulation of the oil flow is infinitely variable Incorporated n the hydraulic system s a regulating valve which maintains a practically constant rate of piston movement Control by this valve allwows extensometer readings to be taken.

Evaluating Proof Stress : Electronic Extensorneter : MCE 2 is a strain gauge type, extensometer to measure material extension with a resolution of 1 micron. It is designed to be clamped directly on specimen. This is used to measure strain up to elastic limit to determine important parameters like 1% to 1% proof stress and Young's modulus, MCE 2 has two fixed gauge lengths of 25mm and 50 mm. Change of gauge length is by means of replacing button knife-edge extender, MCE 2 is fabricated from high strength fight weight aluminium with a durable anodized finish. The knife-edges are made from oil hardened tool steel to withstand heavy usage. Supports maximum dia of 40mm & maximum extension 2mm

Panel Control Mode : Micro processor panel works independently. It shows load, disp. and extension on control panel. It has membrane keyboard or data entry. All specimen related parameters can be entered In to the control panel. At the end of the test one can entered see all test results on front penal display. Load vs Disp. graph can be directly obtained on dot matrix printer.

Servo Control System for UTM with Stepper : MCS has developed unique system Io add servo control facility to UTM. The system contains following.
Motorised servo valve with following items :
• Hydraulic loading valve
• Stepper motor, capacity 20 kg-cm
• Power card for stepper motor
Windows based software for controlling servo valve
MCS Make Centrol box with Auto / Manual selection
Potentiometer for operating valve in manual mode

Every UTM Thas manually operated hydraulic valve. which controls rate of loading. It is very difficult to achieve required rate of loading manually. Due to stringent testing requirements, it is required to conduct tests at specified load rate or strain rate. MCS has developed servo system where above loading valve is converted into a motorized valve by using stepper motor. A special windows based software controls this valve and the operation of the machine.

Servo Controlled operation :
There are two models fo operation. In manual control moe, the machine is operated by means of potentiometer provided on control box. Here, no rate control is offered. The machine is operated by means of potentiometer in similiar ways as we operate hydraulic valve.

In auto control mode, operator enters required load / Disp / Strain rate on computer. When we start the test, the required rate is always compared with achieved rate and error feedback controls machine accurately.

Following rate control modes are available :
• Load rate control : 1 kN to 10 kN per sec
• Displacement rate control : .01 mm to 1 mm per sec.
• Strain rate control : 0.001% to 0.01 % per sec. (strain rate control is possible only with extensometer)

Servo Control with MOOG Valve:
Instead of stepper motor, a MOOG valve can be used for precise load rate control
