Abstract

There is disclosed a method ( 400 ) of operating a molding system ( 100 ), the method ( 400 ) executable by a controller ( 140 ) of the molding system ( 100 ). The method comprises appreciating ( 402 ) a plurality of operational parameters associated with the molding system ( 100 ); based on at least a sub-set of the plurality of operational parameters, generating ( 404 ) a machine performance index, the machine performance index being a single value representative of the at least a sub-set of the plurality of operational parameters and being instrumental in enabling an operator of the molding system ( 100 ) to appreciate an economic productivity factor associated therewith; causing ( 406 ) the machine performance index to be displayed on an interface of the controller ( 140 ).

Claims (37)

1. A method of operating a molding system, the method executable by a controller of the molding system, the method comprising:

monitoring, using one or more monitoring devices, a plurality of operational parameters associated with performance of the molding system, wherein the operational parameters comprise machine variables detectable by the molding system;

based on at least a subset of the plurality of operational parameters, generating a machine performance index, the machine performance index being a single value representative of the at least a subset of the plurality of operational parameters and being instrumental in enabling an operator of the molding system to appreciate an economic productivity factor associated therewith, wherein the machine performance index is generated as a ratio such that operational parameters having increasing value with increasing numeric count are in the numerator of the ratio and operational parameters having increasing value with decreasing numeric count are in the denominator of the ratio;

obtaining a target performance index associated with the molding system, the target performance index being an indicator of desired performance level of the molding system;

normalizing the machine performance index in accordance with a scale comprising a plurality of zones, each zone defining a performance value; and

displaying, via a user interface associated with the molding system, a graphical representation of the normalized machine performance index, the graphical representation including a graphical indicator showing a current level of the normalized machine performance index as a percentage of the target performance index, the percentage of the target performance index comprising one of the plurality of zones.

2. The method of claim 1 , wherein the plurality of operational parameters includes a subset of: (i) cavitation, (ii) uptime, (iii) cycle time, (iv) energy consumption, or (v) part weight.

3. The method of claim 2 , wherein the plurality of operational parameters includes: (i) cavitation, (ii) uptime, (iii) cycle time, (iv) energy consumption, and (v) part weight.

4. The method of claim 1 , further comprising one of (i) receiving an indication of said target performance index from an operator; (ii) accessing a memory of the controller storing the indication; and (iii) accessing a memory tag associated with a mold used in the molding system and retrieving the indication.

5. The method of claim 1 , further comprising in response to receiving an input from an operator, causing the user interface to display a performance index break down indicator, the performance index break down indicator showing a respective performance indicator associated with at least two of the plurality of operational parameters.

6. The method of claim 1 , wherein the plurality of operational parameters includes (i) cavitation, (ii) uptime, (iii) cycle time, (iv) energy consumption, and (v) part weight, and wherein generating a machine performance index comprises applying the formula:

MPI

where MPI is the machine performance index.

7. The method of claim 6 , further comprising weighting the plurality of operational parameters when generating the machine performance index, wherein the weighting includes applying exponents to one or more of the plurality of operational parameters.

8. The method of claim 1 , wherein said machine performance index representative of a first economic productivity factor, and wherein the method further comprises generating a second machine performance index representative of a second economic productivity factor.

9. The method of claim 8 , further comprising displaying, via the user interface, the second machine performance index.

10. A controller of a molding system, the controller having a user interface, the controller being configured to:

monitor, using one or more monitoring devices, a plurality of operational parameters associated with performance of the molding system, wherein the operational parameters comprise machine variables detectable by the molding system;

based on at least a subset of the plurality of operational parameters, generate a machine performance index, the machine performance index being a single value representative of the at least a subset of the plurality of operational parameters and being instrumental in enabling an operator of the molding system to appreciate an economic productivity factor associated therewith wherein the machine performance index is generated as a ratio such that operational parameters having increasing value with increasing numeric count are in the numerator of the ratio and operational parameters having increasing value with decreasing numeric count are in the denominator of the ratio;

obtain a target performance index associated with the molding system, the target performance index being an indicator of desired performance level of the molding system;

normalize the machine performance index in accordance with a scale comprising a plurality of zones, each zone defining a performance value; and

display, via the user interface, a graphical representation of the normalized machine performance index, the graphical representation including a graphical indicator showing a current value of the normalized machine performance index as a percentage of the target performance index, the percentage of the target performance index comprising one of the plurality of zones.
