CNC machining allows for achieving high precision, but the final and mandatory stage of production remains the inspection of finished products. Checking turned workpieces after machining is necessary to identify deviations that may have occurred due to tool wear, thermal deformation, or errors in the control program.
The inspection process typically includes several key stages:
Visual Inspection: Checking for the absence of burrs, chips, signs of corrosion, or mechanical damage on the surface.
Measurement of Geometric Parameters: Controlling diameters, lengths, thread pitch, and angular dimensions using micrometers, calipers, gauges, and Coordinate Measuring Machines (CMMs).
Surface Roughness Check: Assessing surface quality (Ra, Rz) using profilometers, as the finishing quality directly affects the operational properties of the part.
Timely and precise inspection helps prevent defects, reduce production costs, and guarantee full compliance of parts with customer drawings. Regular measurements also help to quickly adjust cutting parameters and extend tool life.
