Experiment No 9 Determination of geometry and dimensions of given composite object / single point tool, using profile projector and tool maker’s microscope.
Experiment No. 9 Title: - Experiment on tool maker’s microscope Aim :- Study and Application of Tool Maker's Microscope . Apparatus :-Tool maker’s microscope, specimen. Theory: - Introduction:- The tool maker’s microscope is a versatile instrument that measure by optical means with no pressure being involved, thus very useful for measurement on small and delicate parts. It is designed for: a) Measurement on parts of complex form e.g. - profile of external thread, tool, templates, gauges, etc. b) Measuring center to center distance of holes in any plane. c) A variety of linear measurements. d) Accurate angular measurements. [1] Use of Tool Makers microscope for screw thread parameter measurement. Use of profile projector for screw thread parameter and slot dimensions measurement. Please see the video animation for working of all the parts of Tool Maker's Microscope Tool maker’s microscope is shown in fig. The optical head can be m
