Parameters used in cost modeling.
Denotation | Definition |
---|---|
CCM (20k) | “Total unit cost” in CM_20k case |
CCM (100k) | “Total unit cost” in CM_100k case |
CAM_method_A | “Total unit cost” in AM method_A case |
CAM_method_B | “Total unit cost” in AM method_B case |
n | “Part counts” |
O | “Other unit cost” in production, which is a very small amount and volume independent This is the summation of CM assembly, operator, and materials; the machine cost approaches 0 independent of the batch size; and the “O” value is assumed to be the same for both CM_20k and CM_100k |
TCM (20k) | “Tooling unit cost” (mold design cost breakdown + mold cost) in CM_20k case |
TCM (100k) | “Tooling unit cost” (mold design cost breakdown + mold cost) in CM_100k case |
M | “Mold design cost,” which is one time cost per batch, a constant, and volume dependent |
m | “mold unit cost” in production, which is a constant and volume independent |
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
