Introduction
Custom automation workshops produce non standard mixing laser processing and material forming equipment fixtures with complex three dimensional structures. Improper evaluation of cmm equipment leads to purchased coordinate measuring machine failing to detect fixture spatial tolerance, bringing long term hidden production cost loss. This article lists all necessary evaluation standards before purchasing cmm equipment for custom automation production.
Accuracy parameter serves as the primary evaluation standard of cmm equipment for custom automation workshop use. Fixtures matched with planetary centrifugal mixer and three roll mill demand micron level volumetric error control of coordinate measuring machine. Laser cutting automation assembly fixtures with ultra tight tolerance need high precision grade cmm equipment, while general material forming fixtures can select standard precision models to control procurement budget.
Maximum outline dimension of non standard automation fixture decides cmm equipment stroke specification, reserved extra measuring space avoids repeated clamping of oversized large fixture frames. Deep cavity fixture structures used in slurry molding lines require extended long distance probe for cmm equipment, multi curved surface laser automation fixtures need multi angle rotating probe to complete full hidden surface detection without dead angle.
Mature cmm equipment carries measuring software compatible with mainstream industrial drawing formats of custom automation industry, supporting automatic batch fixture measurement and inspection report export. Custom automation workshop managers need to confirm long term free software upgrade service of cmm equipment suppliers. Without stable software maintenance, coordinate measuring machine cannot adapt continuous new fixture drawing version updates of non standard production workshops.
