The technologies that are transforming the manufacturing industry in 2024 and beyond

3D printing: 3D printing, also known as additive manufacturing, can create complex and customized products with less material waste, lower production costs, and faster delivery times. It can also enable on-demand manufacturing, mass customization, and distributed production which is a game changer in r&d and small batch production.

Robotics and automation: Robots can perform various manufacturing tasks, such as assembly, painting, welding, and inspection, with high speed, accuracy, and efficiently. They can also reduce human intervention, labor costs, and errors and lead the efficiency in production.

The Internet of Things (IoT): IoT can connect and collect data from sensors on the factory floor and industrial equipment, enabling real-time monitoring, optimization, and automation of manufacturing processes. It can also improve supply chain visibility, product quality, and predictive maintenance, help in decision making and optimize the business processes efficiently.

Limitations of VAVE in Indian Domestic Market

Similar to other technique, value engineering has its own limitations. The most common limitations are that the man-made excuses are the blocks in implementing these plans of value engineering. The most common limitations are as follows.

·       Lack of motivation
·       Resistive to change or adopt new techniques
·       Inertia to do something innovative
·       Lack of knowledge and patience
·       Attitude of ‘It will not work in India
·       We are very small or very big industry
·       This has been tried earlier and failed
·       The change is too big
·       Let competitors try before we try
·       Difficulty of teams meeting or team meeting for getting consensus

 

How to write project description for PMP exam or any other presentation; sample of new product development automotive project description within 200 to 500 words ?

Every project document must have objective so it is project description document and objective is ultimate goal of the project.

 

Project Objective: Complete the product (Shift Tower; an automotive transmission shifting shifting system component) development within given time line and standard of requirement of the OEMs client and base line budget. 

Initiation: Identify key deliverables, risk, assumptions, and constraints in high level of planning. Plan all these high level of task under the the project charter document. Study RFQ drawings, CAD data and plan high-level meetings in order to take approval of project charter. 

Planning: Study of detailed project requirements, constraints, and assumptions with stakeholders and created activity list, resources and activity duration. Conducted kick-off meeting where communicated the start of the project, deliverables and the key milestones. Planned the scope of the project while considering time, cost and quality base lines. Created the work breakdown structure, decomposed and sequenced activities, and developed the project schedule, estimated budget. Defined roles and responsibilities of the project team members to create the resources management plan. 

Execution: Manage project resources, develop and integrate prototypes. Monitoring project progress using PMIS and communicating project status to all the stakeholders. Managed, motivated and led the project team throughout the execution of the project. Conducted weekly project review (PRM) with teams and key stakeholder in order to audit project quality. 

Monitoring and Controlling: Monitor and assess the risk of deliverable, change control system. Review issue logs and update to the stakeholders. Ensured project deliverables conformed to project scope and quality plan. 

Closer: Obtained stakeholders acceptance and created a closure of the project. Created and shared the final project report signed by the concern people as per the communication management plan. Documented lessons learned (TGR/TGW) and conducted a project review to update the organization’s knowledge bank, archived final project documents in order to develop a better document control of the project. 

Outcome of the Project: Product (shift tower) developed and Tested for assembly as per standard of requirements. Outcome and objective should be align and same because your project outcomes define the project quality.

DISTORTION IN CARBONITRIDING AND NITRO-CARBURIZING HEAT TREATMENT PROCESS

 Hardening of a material is to be done to increase the strength and wear properties.

Case Depth = Distance from Surface to Hardness Limit

Distortion is the major concern in heat treatment process and it is the unexpected or inconsistent change in size and shape of the part.

Size distortion is the result of changes in the metallurgical structure that accompany phase transformations. In Heat treatment, the volume expansion and contraction associated with the crystal structure results in change to the volume and linear dimensions of the part such as elongation, shrinkage, thickening, and thinning. Shape distortion originate from the applied stresses that exceeds the elastic limit of the material and results change the geometrical form of the part, which can include twisting, bending, and non symmetrical dimensions.

Carbonitriding and Nitro-carburizing are both thermo-chemical diffusion process, which utilize the diffusion of carbon and nitrogen to increase the hardness and wear resistance at the surface. Although, both the processes takes place at different temperatures and lead to distortion in the part. However, the main advantage of nitro-carburizing is the minimal distortion associated with the process due to the absence of the phase transformation from austenite to martensite.

In gas nitro-carburizing, the part is heated at the temperature around 570 degrees Celsius, mixed gases with the main ingredient of ammonia gas is added which creates carbides and nitrides to form a compound layer on the surface of the material and resulting in a diffusion layer underneath. This formative nitride layer improves mechanical properties such as wear resistance and strength of the steel part.

Gas nitro-carburizing process can accommodate the trend towards lightening more compact parts from the popularization of electric vehicles and it is considered more eco-friendly heat treatment method that is why it continues to increase and is adapted by the manufacturing industries.

In carbonitriding, parts are heated in a sealed chamber into the austenitic range around 850 degrees celsius before nitrogen and carbon are added. The part is heated into the austenitic range of temperature, a phase change in the steel’s crystal structure takes place which allows carbon and nitrogen atoms to diffuse into the part.

Experimental Results

Conclusion: The Nitro-carburizing process can be the perfect replacement of carbonitriding heat treatment when low carbon steel(SAE 1010, SAE 1018, IS513 etc) is subjected to the light load applications, close fitting assemblies where wear resistance is required at part surface. Nitro-carburizing of low carbon steel gives you less dimensional changes in size and shape as compared to carbonitriding. The minimal changes associated with nitrocarburizing process lays in lower temperature and lack of phase transformation from austenite to martensite.
