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

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.
  • Testing of assembled spindle units.
  • Bearing failure.
  • Bearing nomenclature & equivalent selection.
  • Spindle Bearing preloading.
  • Preventive maintenance of spindles.
  • Why do spindles fail - Case studies and examples.


The training programme was conducted by Mr. S K Gupta, Former Asst. General Manager, Machine Design & Business Development, Tata Motors Machine tools division, Pune. Industry experts from Ultra Precision Spindles and PI Spindle Service also addressed the programme.

 



Delegates who attended the training programme gave positive feedbacks:

  • " IMTMA initiatives such as these helps us understand new topics and this should continue "
    -  Rambir Singh, Hero MotoCorp
  • " Overall arrangements were good "
    -  Ankit Sharma, L&T - MHPS Boilers


The delegates were also taken to P I Spindle Service India on a plant visit for live demo of spindle dismantling and assembly.


A total of 16 engineers from Hero MotoCorp, L&T MPHS – Boilers, MachTools TechnoServe, and Mahindra Vehicle Manufacturers attended the training programme.

Sheet Metal Dies - Tryout and Proving

Training Programme on

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.


A total of 12 delegates from Allegis Services India, Bosch, ESI Software, Fiat India Automobiles, Indo Toolings, Robert Bosch Engineering and Business Solutions, Royal Enfield, Swastik Tins, and United Gaskets and Components attended the training programme.

Measuring Productivity through OEE

Training Programme on

Measuring Productivity through OEE

 Profitability in any company is determined by efficiency of operation. In lay terms this means how effectively one uses one’s production resources. Overall Equipment Effectiveness (OEE) is a key performance indicator, which measures out of available time how much time is efficiently used in producing saleable goods. OEE is a performance metric compiled from data on machine availability, performance efficiency and rate of quality that is collected either manually or automatically. In most companies bottleneck machines or key machines determine throughput of the process. When a critical machine is inoperable, it brings downstream operations to a standstill. This can negatively affect delivery commitments to the customer, which in turn impacts cash flow and revenue.


Manual collection & processing of data is tedious and at times erroneous. Automatic data collection followed by idle time analysis helps management to continuously monitor productivity on the shop floor and take measures to reduce idle time thereby improving productivity.

Keeping this in view, Indian Machine Tool Manufacturers' Association organized a one day training programme on Measuring Productivity through OEE on 17 July 2015 at IMTMA Technology Centre in Pune.

The training programme primarily focused on:

  • Productivity Metrics using OEE.
  • Losses in Production.
  • Concept of OEE calculation.
  • Common myths in calculating OEE and taking account of losses.
  • Online monitoring of OEE - Software solution for measurement of OEE.
  • Automatic data collection and idle time analysis - advantages.
