material required
The estimated weight of a material component necessary to meet the production targets for a job. There are 3 primary formulas for calculating the amount of material required. The formulas are dependent upon whether runners and/or scrap are being re-fed for a job.| · | Whenever runners are being re-fed, then the amount of material required is based upon the number of pieces remaining.
|
| · | If scrap is being re-fed but not runners, then calculations are based upon the number of pieces remaining plus estimated rejects and the amount of excess weight per actual shot size.
|
| · | If neither runners or scrap are being re-fed, then the amount of material required is based upon the number of shots remaining plus estimated rejects.

All calculations take into consideration actual reject percents if a job is current and more than 5% complete. There is one exception to this rule, however. If both runners and scrap are being re-fed, reject information is not applicable.
