Two basic systems are used to allocation of gauge tolerance round the nominal size. These are discussed below: (i) Unilateral System: In unilateral system, the gauge tolerance zone lies entirely with in the work tolerance zone as shown in Fig. 1.67. Due to this work tolerance zone available is only 80%. This system is mostly used in industries.8 Wastes of Lean Manufacturing | MachineMetrics,Jan 25, 2016· Metal cutting, grinding, drilling, boring, and other tasks are all part of machining. And as these activities are all “metal-on-metal,” at some point, something must give. This "give" comes in the form of tool wear, where regular operation means that tools will lose surface, sharpness, and temper over time.PROPERTIES, IDENTIFICATION, AND HEAT TREATMENT,color, spacing, and quantity of sparks produced by grinding.
