AbstractMachines tools are used in many important modern industries especially in workshop and in
manufacturing plant, so it’s very important to study accuracy of this machines to determine and manipulation
errors that accrued by many cases, these errors affect on product accuracy.
The main goal of the research is to study the geometric accuracy for Sharping & drilling machines. During
measurement process for machine tools must be depended several geometric characteristics such as
(Perpendicularity, Parallelism, Flatness…), In this research many testing are made on Opaeha Nehnha drilling
machine & Ctahkoc Tpontenbhbln scraping machine to determine the engineering accuracy of these machines
&also to minimize the errors as much as possible to produce high quality products &minimize the raw
material wastages during manufacturing process. Drilling machine testing contains; testing the worktable
surface, rotation shift and loading shift. Sharping machine testing contains; testing of ram (Tool Head) and
worktable surface. Testing results records in tables explain errors value from standard specifications. The
results show errors in many accuracy testing.
