What is OEE and TPM?
OEE (Overall Equipment effectiveness) is the main performance measure that drives action within Total Productive Maintenance (TPM) and is used by the teams to focus their continuous improvement activities as well as identifying those areas that require resource..
What is a loss tree?
In general, Loss Trees are simply a listing of the losses (inefficiencies) which may exist in a factory production process. Loss Deployment is a cascade process that looks initially at the overall factory losses than increasingly at a more detailed level down to a packing line or a single machine item.
How is OEE calculated?
The OEE formula is calculated by multiplying availability, performance and quality and is represented by a percentage. Finding the OEE of an asset starts with measuring availability, which is calculated by dividing the total run time of an asset by the total planned production time of an asset.
What are production losses?
Production losses can impact small and large companies, and they usually result from unexpected problems that arise during what should be a routine manufacturing process.
What are the six big losses?
The Six Big Losses are a very effective way to categorize equipment-based losses: Unplanned Stops, Planned Stops, Small Stops, Slow Cycles, Production Rejects, and Startup Rejects.
How many losses are considered under TPM?
One of the major goals of TPM and OEE programs is to reduce and/or eliminate what are called the Six Big Losses – the most common causes of equipment-based productivity loss in manufacturing.
What is speed loss in OEE?
The manufacturing process is running, but is running slower than the Ideal Cycle Time. This loss is often called Speed Loss. Reduced Speed is one of the Six Big Losses to OEE and affects OEE Performance.
What are the types of losses?
Types of Losses in a TransformerIron Losses.Hysteresis Loss.Eddy Current Loss.Copper Loss Or Ohmic Loss.Stray Loss.Dielectric Loss.
What is KK pillar in TPM?
Kobetsu Kaizen or the Focused Improvement pillar of TPM addresses both these types of losses with the activities that maximize the overall effectiveness of equipment, process and plant through uncompromising elimination of 16 types of losses and improvement of performance.
What are the 16 losses in TPM?
16 types of loss in gembaSetup Loss. e.g. Change of Dies, machining fixtures etc. … Tool Change Loss / cutting blade losses. e.g. Change of Drill, tap, rammer, cutter etc. … Start up Loss. e.g. furnace, paint shop oven etc. … Reduce speed loss. … Defects and rework. … Management losses. … Operating Motion Loss (OML) … Adjustment & Measurement loss.More items…•
How do you calculate production loss?
Multiply the total number of units you failed to produce by your gross profit per unit. This equals your total downtime losses for the period according to average production rate.
What is good OEE?
An OEE score of 85% is considered world class for discrete manufacturers. For many companies, it is a suitable long-term goal. An OEE score of 60% is fairly typical for discrete manufacturers, but indicates there is substantial room for improvement.
