This paper highlights a simple effective-proven-system of QC meant for machine shop operations. This has been introduced with advantage in a large number of engineering plants with which the authors have been associated through their activities with the Statistical Quality Control Unit, Bangalore. Characteristics of a commonly encountered machine shop are as follows: small batch size; frequent job changes; large variety of components machined; low frequency (say one in 3 months) of job repetition. The QC system described in this paper is tailored to suit this common situation. A detailed procedure is outlined for preparing job cards in advance of manufacturing which will indicate the dominant pattern of operations (e.g., set-up dominant, operator dominant, machine dominant, or component dominant) and the processing capability relevant to the design tolerances. This job card will accompany the operation layout chart and quality alert form. Each form is illustrated in filled-in form to indicate its use. Procedures are also outlined for following the job through the shop with appropriate record-keeping.
