Abstract: The area of customize design gave rise to different machines. Wood engraving or wood router machine is one of the development which can be used to perform operations like drilling, engraving, cutting etc on materials like wood, plastics, acrylics, PCB board etc. This paper discusses the effect of variable factors like spindle speed, feed rate and thickness of material on surface roughness and surface roundness of engraved surface. To calculate roundness or circularity of engraved surface coordinate measuring machine Zeiss Contura G2 is used that has least count of 0.0019 mm. For calculating roughness surface roughness tester MITITOYO SJ 210 is used that has least count of 0.0019 mm. It is found that machine shows 99.8% accuracy for diameter and 99.4% accuracy for height achieved.
