           Heat Treatment:
           •   Plan  the  heat  treatment  process  based  on  the  material  composition,  desired  mechanical  properties,  and
              specific requirements of the drawing tool.
           •   Preheat the drawing tool to a uniform temperature using ovens or furnaces to facilitate the heat treatment
              process.
           •  Perform the primary heat treatment operation, such as quenching, annealing, or tempering, according to the
              recommended temperature and time parameters specified for the chosen material.

           •  Monitor the heat treatment process closely using thermocouples, pyrometers, or temperature controllers to
              ensure uniform heating and cooling rates throughout the tool.























           Finish Machining:
           •   Transition to finer cutting tools such as ball mills, reamers, or broaches to achieve the final dimensions and
              surface finish of critical features.
           •  Implement multi-axis machining strategies, including contouring, profiling, and finishing passes, to ensure
              geometric accuracy and surface integrity.
           •  Employ high-precision measuring instruments such as dial indicators, bore gauges, and surface profilometers
              to verify dimensional accuracy and surface quality during machining.

           •   Implement corrective actions such as tool offsets or toolpath adjustments to address any deviations from the
              desired specifications detected during machining.
