Tech. WORD of the Week: PdM

FULL FORM: PREDICTIVE MAINTENANCE

GRAPHICAL REPRESENTATION:

MEANING: Data from Sensors (internal & external) installed on any type of machine is used to detect symptoms, and PREDICT which problems can occur in future. Action is then initiated to ‘nip the problem in the bud’

The entire process of data collection, analysis & instructions for action is automatic and free from human dependence. It is therefore extremely reliable and works 24×7. 

TYPES of PdM ACTIONS: There are THREE types of actions.

1. ALERTS.

2. INSIGHTS: (An Insight is seeing inner character of underlying truth)

3. AUTONOMOUS ACTION (In situations where there is no time for humans to act)

ADVANTAGE OVER TPM:

• TPM is a more than 50 years old concept which has played a very important role BUT is heavily dependent on humans.
• PdM make use of HUGE ADVANCES in IoT enabled sensors, Cloud based networks and Artificial Intelligence/Machine Learning to achieve ‘magical results’ with minimum human intervention.

OPTIONS for Non-CNC Machines like Forging Presses, Die Casting, De-Coiling, Plastic Injection, etc: PdM can be installed on ANY type of machine, even manually operated. We need to understand basic working of machine and then select and install suitable sensors.

Payback Period (ROI) : 6-10 Months

CONCLUSION: PdM is an absolutely essential Industry 4.0 Technology that will drastically reduce breakdown downtime of machines & result in HUGE SAVINGS :

• Saving in parts that do not need replacement
• Saving in downtime of all machines in the line
• EARNING goodwill of the customer
• PEACE OF MIND for you!
