Answers
Why is an Image Analyzer required?  

Image analysis systems, when used in the laboratory, help to remove judgment in analysis and provide results obtained using mathematical means using objective methods. All software complies with internationally accepted standards like ASTM, JIS, DIN etc. and systems are calibrated using national standards, which is a pre requisite of ISO/QS.

They are also excellent documentation tools and when used effectively, they have direct / indirect effect on :

Quality enhancement
Quality Process optimization
Quality Process transparency (Grey level images)
Reduction in sample checking times, increase in accuracy
Less complaints and returns of material
Product and Company image

What are the advantages of an Image Analyzer over conventional methods? 

Manual Method The MVIG 1005
Comparison method. Actual calculations as per the standards.
Disputes between Metallurgist can occur Disputes between Metallurgist can be solved
Darkroom facility required for photographs and takes a long time to develop the photographs. Darkroom facility not required. Printouts of the image can be received within minutes.
The report has to be made manually and the photographs have to be developed and pasted on the report. The reports can be generated automatically and instantly along with photographs, with tables and graphs of the final results.
Operator fatigue is mainly observed as too much time is wasted in calculations and report formation. Since the reports are generated automatically with all the necessary minute details, the operator is highly motivated to work.
Picture enhancement is not possible. Picture enhancement can be done on-line or with the stored images.
Parameters of the objects are difficult to calculate and it takes hours to calculate. Parameters of the objects in the image such as area, perimeter, length, width etc. is calculated automatically and within minutes.
Too much space is required to store the reports. Reports can be stored on the Hard disk or floppy disks.
Basis for testing and analysis is judgmental and varies from person to person Basis for testing and analysis is tractable to some certified standard by an accredited national laboratory and thus acceptable to ISO.

Some case studies and installations of the MAIG 2000 

Parts Inspection in Automobile Industry
Inspect parts for machining defects and tolerances as they are manufactured. There is no need to take parts to lab. Cycle time can be in seconds for a complete analysis.

System is being developed for a two wheeler manufacturer to check for engine crank case as it is manufactured. It is checked just before engine assembly for surface defects automatically.

Rod diameter inspection in Steel Mill
Any steel mill making steel rods by hot rolling process has to comply with user specifications for rod diameter. Typically, the requirement can be for rod diameter of 25 mm with a variance of 0.1 mm allowed. Traditionally, the manufacturing line is stopped after every 10 rods are made, a sample is cut from a long rod, is cooled down and then checked manually. Our visual inspection system checks the rods for diameter tolerances in real time when the rods are in hot condition. This has a double benefit viz the line does not have to be stopped and the checking is for 100% of the rods produced

Blocked Hole inspection in Printed Circuit Boards
We have supplied a system which checks for blocked or extra holes ( 0.2 mm diameter ) in Printed circuit boards. When a PCB manufacturer supplies a board with a blocked hole to a customer, the auto pick and place machines which insert chips on these boards give errors , as the component gets jammed. These boards are typically 10 inches x 12 inches , having upto 4000 holes. Earlier, these were individually held up against a light source and checked for extra / missing holes. We have designed and installed a system with a light table which can check one board every 2.8 seconds with 100% accuracy.

What is MHT 25C? 

The MHT - 25C is a fully automatic Micro Hardness Tester with a computer controlled X-Y stage, automated indentations and measurements. Report generation is in MS Word.

^ Top
What are the hardware and software components in the MHT 25C? 

Micro Hardness Tester with Auto Indentation and loading
Motorised X-Y stage for automatic Traverse
High resolution B/W CCD Camera and Image Acquisition Card with software Image capture, analysis and reporting Software as per ASTM E 384
Basic Computer and Standard Resolution ( 600 DPI ) Inkjet Printer

^ Top
What are the advantages of the fully automatic MHT 25C over a manual tester? 

Traverse can be programmed in the system.

Typically, for impressions at 10 locations, manual analysis will take upto 45 minutes be completed with a report. There will be a lot of operator fatigue for heavy loads.

As opposed to this, in the automatic system, the machine takes and impressions and then the measurements and then generates the report automatically. This becomes a man less operation and can be completed within 15 minutes.

How is the instrument calibrated? 

Optics are calibrated using a 10 micron scale. This scale is calibrated by the National Physical Laboratory and is used to find the size in microns of a pixel on the monitor.

A calibrated Test block ( imported ) is used to check the repeatability of the instrument.

The weights are calibrated using a load cell and weights , traceable to a national standard.

^ Top
Can a bi directional computer controlled motorised stage be added to any existing MHT? 

Yes, we can add our motorized stage to your existing MHT ( after inspection ) to convert the manual system to a automatic indenting and traverse system

We have carried our such upgradations in the past.
