Engineering & Processing Work Instruction

Control # 110.3 / Rev. / A

I. Purpose

To provide work instructions for Engineering & Processing.

II. Responsibilities

The Engineering Manager has overall responsibility for this procedure.
Estimators, Engineers and Project Managers are responsible for compliance with this procedure at the project, job, or process level.
Where appropriate the Quality Manager shall provide support and review prior to release of manufacturing processes.

III. Definitions

There are three basic types of manufacturing processed at PPC :

Prototype - This type of project or process is experimental in nature. The process is controlled by the engineer and / or the customer. The Project Manager for this job or process has overall responsibility for determining the required inspection, test, process controls and documenting the results.

Production - This type of project or process is often referred to as "Short Run" or ""Production work". This type of work includes tooling, special machines, production and lower volume manufacturing and assembly work.

Assembly / Second Operation - Assembly / Second Operation is either prototype or production for manufacturing with additional assembly process requirements. Reference the assembly/second operation work instructions.

1 Engineering & Processing Procedure

Engineering Reviews:

  • Bill of materials

  • P.O. Requirements

  • All related paperwork

  • Identifies critical characteristics

  • Defines the customer requirements

Contract Review

The engineering review shall address PPC ability to comply with the contract.
The engineer responsible for the contract shall immediately inform the engineering manager of any discrepancies or inability to complete the customer requirements.
The engineering manager or engineer assigned to the project will contact the customer and resolve the problem.
The Engineer assigned to the project shall determine the level of documentation that will be required to meet both the customer and company requirements.
Engineers shall address the requirements for:

  • Safety

  • Regulatory requirements

  • Reliability

  • Quality

  • Efficiency

  • Capacity

  • Cost effectiveness

  • Review and approval of completed designs and processes.


Engineering and Documentation requirements for projects and processes:
Determined by the Project Engineer and Customer. The nature of these projects does not allow for normal process control. Usually concept and experimental projects.


Engineering and Documentation requirements for projects and processes such as Production jobs, Tooling, Machines and Short Run projects that require minimum documentation:

  • Create the process sheet

  • Create step prints (if necessary)

  • Design inspection tooling (if necessary)

  • Design manufacturing tooling (if necessary)

  • Create the first piece report (if necessary)

  • Review the process for customer and company requirements

Should involvement of the customer become necessary, contact the appropriate salesperson who will coordinate any changes.

Review the process for:

  • Is the process safe?

  • Is the quality engineered in?

  • Is the efficiency engineered in?

  • Are the capacity requirements engineered in?

2 Determining Inspection Methods

There are standard inspection procedures detailed in the procedure for production control.
Engineering shall determine the requirements for inspection, testing, methods and instruments to be used.

3 Tooling Requirements

Engineering shall design tooling that is functional and correct for the use it was intended for.
Engineering shall provide proper instructions for qualifying and using said tooling.
All tooling shall be qualified prior to use in production or delivered to the customer.

4 Post Production Review

The Engineering, Department and Quality Managers are responsible for monitoring the success of all engineering and manufacturing processes.
The Engineering, Department and Quality Managers shall collect data on completed jobs, project reports, customer needs, field performance, customer feedback and availability of new technology.
