What is Lean? Principles, Tools In Lean Manufacturing.

By -

What is Lean? Lean meaning: 

  • Lean is the set of tools for identification and elimination of the wastes in the manufacturing systems.
  • Lean is clearly distinguishing the value-added and Non value-added activities.
  • Lean is Reducing the waste and Adding Value to products and services.
  • Lean tools are improving productivity,quality and so as the reduced costs associated.

Thus Lean methodology is doing more with less.


Principles of Lean:

Key principles of Lean Manufacturing for creating effective & efficient organization are as follows-

  • Waste Elimination.
  • Production flow.
  • Pull Processing.
  • Load leveling.
  • Flexibility
  • Automation.
  • Continual Improvement.
  • Vendor development and management.


Pull processing (means 'make to order')  is the strategy of waiting for customer demand and quickly or effectively processing as per demand so that no warehoused inventory of products.


Lean Tools:

Tools for identification and elimination of Wastes in Lean Manufacturing are - 

1. 5S methodology for workplace organization.

2. TPM for continuous improvement.

3. SMED (Single Minute Exchange of Die) For reduced downtime between set up changes.

4. Control Charts 

5. Production Flow Analysis.

6. Value Stream Mapping.

7. Poka-yoke (Error Proofing).

8. Kan-ban for workflow visualization.

9. Multi process handing.

10. Redesigning of work cells.

11. Single-point scheduling.

Basic Work Content And Productivity Improvement.

By -
Factors Affecting Basic Work Content -   Basic work content is the minimum time required for production as per standard rate of working with the help of qualified worker and with perfect design and specifications. The heart of the productivity improvement in any manufacturing organisation is depend on its basic work content. Process of manufacturing is affected by some factors associated with basic work content. Following are the factors affecting basic work content and thus on the productivity. 1.Workmen Efficiency: Workmen enfluencing basic work content in following ways-  Careless workemenship  Accidents by workmen. Absentism of workmen. Idleness of workmen. Lateness of workmen. Indisciplined workmen.   2.Management Shortcomings: Management is also responsible for enfluence on basic work content . Some management shortcomings are as - Design changes. Excess product variety Bad planning. Lack of standardization. Plant Breakdowns.   Bad working conditions...

SMED

By -
SMED: SMED (Single Minute Exchange of Die): SMED  stands for  Single Minute Exchange of Die. SMED (Single-Minute Exchange of Die)  is a Lean tool used in manufacturing to reduce equipment changeover time.  The goal of  SMED  is to complete as many steps as possible while the equipment is running , to save time and quickly change over to processing the next product. The core principles of the  SMED  procedure involve separating changeover elements into two categories. Internal activities and External activities. For  SMED : Internal activities  -  can only be performed when the production process is stopped. External activities-  can be completed while the machine running or upto the actual changeover begins.  SMED  helps in achievement of  rapid setups and minimized downtime by  converting internal activities into external activities. Advantages of the SMED: Reduced changeover times / Reduced Downtime by min...

BOTTLENECK IN PRODUCTION PROCESS- Bottleneck in production process , is a process whose limited capacity reduces, delays or stops the flow of operation and affects the capacity of overall manufacturing processes.   Almost every system has a bottleneck . The machine with the longest queue of accumulated input for processing is usually a bottleneck in production process. It is important to identify the bottleneck machine or process and to remove or reduce the waiting time for next operation so as to achieve the desired targets in manufacturing processes. Here discussed the various types of   bottleneck in production process. Types of Bottleneck in production process: 1.Short-term Bottleneck:  These are caused by temporary problems.  Short-term bottlenecks  do not need regular attention. 2.Long-term Bottleneck:   Long-term bottlenecks occur all the time. These have substantial impacts on the overall manufacturing processes.  Long-term bottl...
