Design for Manufacturability (DFM)

Quality, Cost and Delivery (QCD) are the key elements which make a product successful in the global competitive scenario. Design for Manufacturability (DFM) is a set of guidelines developed to ensure that a product is designed so that it can be easily and efficiently manufactured with a minimum of effort, time, and cost. DFM will help designers to build quality into robust design at least cost. In addition to achieving quicker product development and reducing cost of product development, DFM also ensures that the transition from the design phase to the production phase is as smooth and rapid as possible.

 
 

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) had organized a 2 day programme on Design for Manufacturability (DFM) on 5 and 6 January 2016 at IMTMA Technology Centre in Pune.

Cleaning of Machined Components

Parts cleaning, like most metalworking processes, are experiencing ever tightening specifications. Owing to the constantly increasing requirements in terms of efficiency, quality and environmental protection the cleaning of industrial parts has become absolutely essential in modern manufacturing processes. It is highly critical especially in case of automotive components, aerospace parts and medical implants.

However, Parts cleaning is often the most ignored area in the production lines. Cleaning is commonly considered as non value adding process; without evaluating the consequences of ignoring component cleaning. A successful cleaning process requires careful selection of both the cleaning chemistry and equipment. Cleaning process is influenced by various factors viz. manufacturing process, cleaning media, surrounding conditions, work-piece quality, parts handling, machine technology, testing process (Millipore test), etc.

 

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) had organized a 2 day programme on Cleaning of Machined Components on 4 and 5 February 2016 at IMTMA Technology Centre in Pune.

The training programme focused on :

  • Importance of industrial parts cleaning.
  • Cleanliness testing methods.
  • Inspection procedure in determining cleanliness.
  • Different types of cleaning media; Selection of right cleaning media.
  • Important factors influencing cleaning results; Influence of surrounding conditions.
  • Combining cleaning technologies; multi-stage cleaning systems using automated material handling.
  • Ultrasonic cleaning processes.
  • Cleaning Chemistry - Insight and recent trends.
  • Cleaning of automobile parts - user perspective.
  • Live demo of ultrasonic cleaning equipment.

This programme was conducted by industry experts in Surface Coating & Application Technology from SKF India, Castrol India, NN Combined Engineering Agencies, Crest Ultrasonics India, and Durr Ecoclean.

A total of 35 delegates from Cabrorundum Universal, Central Tool Room and Training Centre, Schoch Reeds India, Ferromatik Milacron India, FALCON TOOLINGS, M/S P.A. Pinions,Tractors and Farm Equipment, Bajaj Steel Industries, Panchsheel Filters, Gautam Technocast, Sartorius Stedim India, Silkaans, ELGi Equipments, Bajaj Auto, Jayahind Industries, Force Motors, Essem Tecnopinz, Mahindra & Mahindra, Hydac (India), and Micro Supreme Auto Industries attended the training programme.

Workholding and Fixturing Clinic for Production Engineers

Innovative solutions in workholding and fixturing result in defect free and smooth production. Their optimum use not only improves productivity but eliminates quality defects. Often problems related to poor quality and productivity are a direct consequence of poor fixturing in terms of its choice or design. Reduction in set-up change is a challenge most manufacturers face and this is directly related to quality of fixturing.


Keeping this in view Indian Machine Tool Manufacturers' Association (IMTMA) organized a 2 day programme on Workholding and Fixturing Clinic for Production Engineers on 14 - 15 July 2015 at IMTMA Technology Centre in Pune.

The training programme primarily focused on :

  • Trends in fixturing.
  • Work holding solutions for CNC Turning applications.
  • Interactive group discussions on fixture design concepts.
  • Design of Pneumatic / Hydraulic fixtures for volume production.
  • Single Minute Exchange of Dies (SMED).
  • Innovative work holding solutions.
  • Lead time reduction using standard / modular fixture elements.
  • Group exercises on fixture design, problem solving and trouble shooting.


The training programme was conducted by experts from Kennametal India, Schunk Intec, Jergens India, Halder and Mr. Gautam Doshi, Advisor IMTMA. Eight delegates from Aequs, Aurangabad Electricals, Bajaj Auto, Greaves Cotton, Hindustan Aeronautics, and Mahindra & Mahindra attended the training programme.

Spindle Maintenance for Metal Cutting & Industrial Machinery

Spindle Maintenance for Metal Cutting & Industrial Machinery

Maintenance of spindles in metal cutting or industrial machinery is a critical function of a maintenance engineer. Technicians maintaining them typically require special diagnostic tools and intense technical training. Often component deviations can be traced to faulty spindles. Spindle maintenance requires a thorough knowledge of bearing application, lubrication, assembly tools and techniques.


Keeping this in view, Indian Machine Tool Manufacturers' Association organized a 2 day programme on Spindle Maintenance for Metal Cutting & Industrial Machinery on 8 and 9 January 2016 in Gurgaon.

The training programme focused on:

  • Bearing types & their application in metal working and industrial machinery.
  • Bearing lubrication systems.
  • Spindle failure & reconditioning.
  • Tools, tackles & assembly techniques.

Sheet Metal Dies - Tryout and Proving

Sheet Metal Dies - Tryout and Proving

 Die Tryout and Proving is one of the most important and critical step in the manufacture of Sheet Metal Dies. There are many variables which contribute to the successful completion of this activity. Tool makers who are responsible for executing this step traditionally learn a lot from trial and error methods. After accumulating many years of experience in this activity, they finally begin to exert sufficient command over this domain. Nowadays use of simulation software have considerably reduced the time taken for this activity. However, this activity has to be necessarily fine-tuned and the final component produced on the Press.


The Component Design, the Die Design, the Material Properties, the Die Manufacturing Process and the Press itself are some of the variables and all of them play a vital role. Understanding the impact of each of these variables and pin pointing the root cause to correct the component is quite a complex activity.

Keeping this in view, Indian Machine Tool Manufacturer's Association (IMTMA) organized a 3 days programme on "Sheet Metal Dies - Tryout and Proving" on 23 - 25 November 2015 at IMTMA Technology Centre in Pune.

The training programme primarily focused on :

  • Preparatory activities to be done before Die Tryout.
  • Carrying out static and dynamic checks to confirm proper assembly and working of the Die
  • Steps in the tryout process which are critical from the Quality Perspective.
  • Different types of defects in components and methods of overcoming them.
  • Understand the different variables which contribute to defects.
  • Identifying the root cause of defects.
  • Importance and various methods of scrap shedding.
  • Practical demonstration of all the above points in a tool room manufacturing Dies and in a Press Shop


The training programme was conducted by Mr. C A Bodas, industry expert in Die Manufacturing, Tryout and Proving of Sheet Metal Dies with more than 30 years of practical hands on experience in Tata Motors.
