Chemical Machining is the process of removal of material from the workpiece using chemical reactions by immersing the workpiece into a chemical solution.
Chemical Machining is a process used for metal removal purpose by dissolution in a controlled manner from the workpiece by the application of acidic or alkaline solution and this solution is called etchant.
The chemical machining process is widely used to produce micro-components for various industrial applications like micro electrochemical systems (MEMS) and semiconductor industries.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

*CM consist several steps with its unique sequence
6. Chemistry of Chemical Machining
• Cleaning:
It is the first step in which we clean material from any other pollutants
• Masking:
The protective layer is applied to the material which is resistive to our etchant*
• Etching:
This is the material removal step, converts work material into salt, wash the part
to stop further process
• Demasking:
The maskant is remove from the part
*(strong acid)
7. Masking Methods
Maskant material includes neoprene, polyvinylchloride, polyethylene
and other polymers. Masking can be achieved by any of following
three methods
1. Cut and Peel:
Apply maskant over entire part by dipping, spraying or painting, maskant
thickness (0.025 to 0.125 mm). After hardened maskant remove by hand using
scribing knife, usually with a template. It is used on large work parts and low
production where accuracy is not a critical factor. Maximum tolerance we can
achieved by it is (±0.125 mm).
8. Masking Methods
2. Photographic Resist:
Uses photographic techniques to perform the masking step. The masking
material contain photosensitive chemicals. Negative image of the desired areas to
be etched. Maskant can be remove through photographic developing techniques.
This process is normally applied where small parts are produced in high
quantities and close tolerance are required. Tolerance closer than (±0.0125 mm)
can be held.
9. Masking Methods
3. Screen Resist:
The maskant is applied by the means of silk screening method. In this maskant
is painted on the work part surface through a silk or steel mesh. Stencil protects the
area.
The screen resist method is generally used in applications that are between the
other two masking methods in terms of accuracy, part size and production
quantities. Tolerance of (±0.075 mm) can be achieved with this masking method.
10. Etching Process
• Etchant depends on work material, desired depth, rate of material removal and
surface finish requirements
• Etchant must also be matched with the type of maskant
• Material removal rate is CHM are generally indicated as penetration rates
(mm/min)
• The penetration rate is unaffected by surface area
• Depth of cut in CHM is 12.5 mm for aircrafts panels made out of metal plates
• There is also undercut
• Etch factor : Fe = d/u
15. Chemical Machining Processes
1. Chemical Milling
• It’s the first processes to be commercialized
• World War II, Aircraft Company, US, “chem-mill”
• Still used in Aircraft Industry for weight reduction
• Applicable large parts
• The cut and peel maskant method is used
• Surface finish varies with material removal rate
• Metallurgical damage is very small perhaps around (0.005 mm) into the work surface
18. Chemical Machining Processes
2. Chemical Blanking
• Uses Chemical erosion to cut very thin sheet metal parts – down to (0.025 mm)
• Conventional or punch die methods does not work
• Damage sheet metal, tool cost will be high
• Parts produce by this method is burr free
• Photoresist or Screen resist method
• For small or intricate we use photo resist
• Tolerance closes ±0.0025 mm can be held
• In screen resist the masking procedure provide accurate registration between two sides
• Limited to thin or intricate pattern, maximum stock thickness 0.75 mm
• Hardened and brittle materials can be processed
20. Chemical Machining Processes
3. Chemical Engraving
• Name plates and other flat panels
• Lettering and Artwork on other sides
• Either recessed or raised lettering
• Masking is done by either Photoresist or Screen Resist
• Except filling operation follows etching
• To apply paint ant other coating in recessed area
• The effect is to highlight the pattern
21. Chemical Machining Processes
4. Photochemical Machining
• Photoresist method of masking is used
• Applied to Chemical Blanking and Chemical Engraving when these metods use
Photographic resist method
• Used for close tolerance and intricate patterns
• Used in electronic industry to produce intricate circuit design
• There are various to photographically expose the desired image onto the resist
• Photoresist materials is sensitive to ultraviolet light
• No need to carry out procedure in the dark room
• In this procedure etch factor is known as anisotrophy
