Control of the use of conventional machining materials in engineering majors has not been well controlled. Waste of costs by budgeting new work pieces for each new type of work is valued as a swelling of operational financing practices. Through the efficiency of material consumption that is sustainable in conventional machining practices can streamline the process, save time and cost of production, and maximize the use of old or used work pieces to develop 11 competencies achieved. By comparing five jobs in machining practice in VHS with a job called job modification capable of providing 30% efficiency of operational costs, a time required, and more minimalist material consumption while still attending to the achievement of competencies. The research analysis uses design assistance and iProperties in Autodesk Inventor 2012 software. © Published under licence by IOP Publishing Ltd.
