SMT-CTL-001  Cut to Length Procedure

Cut to Length Procedure

 

1.     Print out of pick list or Cut to Length Line schedule to be used to stage coils in order of use. If lineup is changed, Production Planner or Plant Manager will notify Operator and correct schedule.

 

2.  Skid list is created per schedule and given to appropriate personnel.

 

3.     Using W/O's "Order spec" sections to determine sizes and leveler settings that will be input into CTL Line.

 

4.     Coil loaded onto CTL by appropriate personnel, tag is given to operator to verfiy correct coil is fed up per W/O.

 

            Frequency of Quality Measurements (BURR, WIDTH, CAMBER, FLATNESS, LENGTH, SQUARE) Record on FOP 081

Tolerance Type Minimum Inspection Frequency
TIGHT TOLERANCE
+/- 0.062" or tighter for LENGTH, WIDTH, or SQUARE
1/8" or less for FLATNESS
 CHECK SAMPLE PRIOR TO PUTTING LINE IN RUN + CHECK PIECE ONCE LINE RUN IS ESTABLISHED + LAST PIECE OF 1ST BUNDLE + LAST PIECE OF SKID AFTER EVERY 7,000 LBS + LAST PIECE OF RUN
STOCK TOLERANCE Greater than +/- 0.062" for LENGTH, WIDTH, or SQUARE
Greater than 1/8" for FLATNESS
CHECK PIECE ONCE LINE RUN IS ESTABLISHED + LAST PIECE OF 1ST BUNDLE + LAST PIECE OF SKID AFTER EVERY 14,000 LBS + LAST PIECE OF RUN

5.     Operator checks gauge (edge-crown-edge) on first and last bundle produced and Rockwell (if required) from first bundle only. All other measurements are taken according to the table above by Operator & Helper.

 

     6.        If work order/part spec says "Residual Stress Check", then check residual stresses per SMT-SH-001.

7.   Visual inspection for BURR, WIDTH, CAMBER, FLATNESS, LENGTH, SURFACE QUALITY, SHAPE Performed on every bundle, not recorded.

 

8.   If any check does not meet the Customer Part Specification/Job Requirements, QA is notified and will contact sales.

 

9. Sales to contact customer for deviation. If customer accepts deviation, then JDM100 (Deviation Request Form) will be filled out and signed (email or verbal acceptance is acceptable and should be documented by sales) and OK is noted on FOP 081 and/or work order. If customer does not accept deviation, the Production Planner is notified so replacement can be made and material is placed in reject warehouse for MRB disposition.

 

10. CTL Product is packaged according to W/O & Part Specification, weighed, tagged, and moved to appropriate warehouse.

 

11. At packaging, appropriate personnel will write tag number on bundle to be visible where tag is hung.
