At Dakings, these factors are considered together when reviewing a precision machining project.\r\n        <\/p>\r\n\r\n        <h3>Machine Capability<\/h3>\r\n\r\n        <p>\r\n            Machine accuracy, rigidity, repeatability, spindle performance, and overall condition affect how consistently a CNC machine can produce a specified feature. The machine must be capable of meeting the required tolerance before production begins.\r\n        <\/p>\r\n\r\n        <h3>Material<\/h3>\r\n\r\n        <p>\r\n            Different materials respond differently during machining. Hardness, thermal expansion, residual stress, and machinability can influence dimensional stability and may require different cutting strategies or additional process control.\r\n        <\/p>\r\n\r\n        <h3>Tool Wear<\/h3>\r\n\r\n        <p>\r\n            A worn cutting tool can change feature dimensions, increase surface roughness, and reduce consistency. For tight-tolerance parts, tool condition and replacement intervals need to be controlled throughout production.\r\n        <\/p>\r\n\r\n        <h3>Fixturing<\/h3>\r\n\r\n        <p>\r\n            Stable workholding prevents unwanted movement and deformation during machining. Proper fixturing is especially important for <strong>thin walls, long parts, complex geometries, and tight-tolerance features.<\/strong>\r\n        <\/p>\r\n\r\n        <h3>Thermal Stability<\/h3>\r\n\r\n        <p>\r\n            Heat generated during cutting and changes in ambient temperature can cause thermal expansion in the machine, tooling, and workpiece. Stable machining conditions help maintain dimensional consistency during precision production.\r\n        <\/p>\r\n\r\n        <h3>Part Geometry<\/h3>\r\n\r\n        <p>\r\n            Deep pockets, thin walls, small holes, long features, and complex surfaces can be more difficult to machine accurately. Geometry can affect tool accessibility, vibration, workholding, and the number of machining setups required.\r\n        <\/p>\r\n\r\n        <h3>Inspection Method<\/h3>\r\n\r\n        <p>\r\n            The inspection method must match the required tolerance.
