Precision Production MachiningPrecision production machining is an important player in the production of high-accuracy and high-quality components.  It is one of the most important techniques used in industries today and used for shaping tools and parts to their highest-possible level of accuracy and tolerance.

This process is capable of handling many types of metals. Different cutters are used based on the material in use such as solid cutters, laser cutters or even water cutters in order to provide the optimum levels of accuracy. 

Steps Need To Be Taken to Protect High-Levels of Accuracy 

When looking for a production machining partner, you need to consider a range of issues beginning with the application.  The OEM should always partner with a vendor who is fully-qualified to work within the required component material. Be sure to consider the vendor’s equipment and level's of expertise. 

For higher standards of intricacy or tighter tolerances, the OEM will need to inquire about the experience levels of the vendor for specific applications or industry-critical requirements. 

To run an advanced production, quality equipment like CMM's which are used to inspect parts for dimensions are needed. Another consideration includes the vendor's ability to provide any pre or post production services like engineering assistance, assembly or packaging that may be required for your project. 

Precision production machining is used to manufacture or fabricate the injection molds or tools needed to produce plastic components. To this end - production machined products sells an hour on a piece of production equipment.

Hours Report Definitions:

    • Capacity Hour – this refers to the number of production machines under roof multiplied by the scheduled hours.
    • Off-Line Hours – this is the number of machines that remain off-line for rebuilding, etc.
    • Available Hours – the number of hours available for production
    • Process or Machine Hour – the total number of hours machine is either being set-up or producing parts, including the operator downtime hours
    • Management Downtime Hours – this is the amount of time the machine is not running because of conditions beyond the control of the operator
    • Set-Up Process Hours – these are the total number of hours used on set-up during the shift
    • Running Time – the total number of hours production machining is producing parts
    • Operator Downtime Hours – operator downtime is the non-producing time that is a result of sharpening tools, adjusting, oiling, warming-up, etc.
    • Production Process Hours – the sum of running time + operator downtime
    • Quoted Hours – the cycle times of a machine required in order  to complete all of the operations that were reduced by operator downtime
    • Produced or Earned Hours – the number of hours necessary to produce an actual run of good parts
    • Man-Hours Worked – the total number of skilled man-hours that are required when machines are either being set-up, or producing parts including any operator downtime hours
    • Management Downtime Man-Hours  - the amount of time spent when operator is not running any machine because of conditions beyond the control of the operator
    • Payroll Hours – the amount of time actually worked - based on payroll records

The single greatest impact a production manager can have on productivity is knowing exactly how time is being spent on the manufacturing floor.  In the precision-turned parts industry, most machine cycle times are measured in seconds. 

The two components of minutes – machine hours and labor hours are key measures for productivity and profitability.  Machine hours are primarily driven by customer demand and labor hours are controlled by company management. 

These are only a few of the reasons it is of vital importance to carefully choose your production machining-partners or other vendors.
