The text covers the calibration of the volumetric workspace of the multi-axis smoothing cell using ISO standard tests with the aim of studying the effects of thermal influences. Plane axis motions errors were measured with a laser interferometer and multi-axis volumetric measurements were carried out with a 6 axis laser tracker. The thermal variation is assessed during operation at high heat load for this type of operation. A Matlab based thermal error model is developed and validated to simulate thermal errors over a range of operating parameters. Using the model and experimental data, direction was given to optimise the robotic cell performance and is due to be implemented for further use\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659832390\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659832390","offer_id":39449972768861,"sku":"9783659832390","price":54.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c6c58709-f3e3-463a-83bd-265594582f81.jpg?v=1769234470","url":"https:\/\/shop.autorenwelt.de\/en\/products\/thermal-performance-of-a-multi-axis-smoothing-cell-von-charalambos-georgiou-paul-comley","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
