PREVENTIVE MAINTENANCE OF TOOLS
A List of tools is prepared and maintained.
Tools are identified with unique numbers / locations for safe storage & easy retrieval.
Prepare preventive maintenance check sheet for all press tools.
Carryout tool verification as per decided frequency in Tool PM Module and monitor the tool life by monitoring quantity produced by that tool in each die loading and unloading time.
The inspection of tooling involves the following:
a) Verification of tool with respect to boundary dimensions, where applicable.
b) Visual Inspection of tool for surface finish
c) Tool is mounted and process is run at flow rates matching production situation to produce part/component.
Accordingly based on tool and part inspection using calibrated instrumentation, the tool is accepted/rejected and same endorsed on Tool history card.
Inventory of Non-consumable /non-perishable tooling is controlled through Tool History card.
If tools are to be rejected / reworked then the same is identified accordingly and kept in designated area.
