Analysis and stiffness evaluation of a microparallel kinematic machine

This study explores a scaled version of a 3-PRRR parallel configuration that can be used in micro-machining tasks. The study addresses a stiffness model of a micro-parallel kinematic machine (mPKM) by employing an approach involving kinematic and static equations. The objective of the model includes...

The study addresses a stiffness model of a micro-parallel kinematic machine (mPKM) by employing an approach involving kinematic and static equations. The objective of the model includes providing an understanding of the manner in which the stiffness of a mechanism changes as a function of both the position of an end-effector and the estimated cutting forces that are generated by micro-machining operations. An experimental prototype is considered for the preliminary validation. Three work planes and three cutting directions into the workspace are evaluated by iso-stiffness mapping. The results indicate that the mPKM operates with high stiffness performances in static operations. This is useful for suitable improvements in the prototype and developing analytical design criteria.Este trabajo explora una versión escalada de la configuración paralela 3PRRR para ser usada como micromáquina herramienta. Se propone una metodología para obtener mapas de rigidez mediante un modelo teórico y un prototipo experimental. El objetivo principal es definir un conjunto de directrices que permitan, a su vez, establecer criterios de diseño. Se presenta un modelo de rigidez basado en la teoría de trabajo virtual con el propósito de comprender como cambia la rigidez de la máquina en función de la posición del actuador final y las fuerzas de corte generadas por una operación de micromaquinado. Tres planos de trabajo y tres direcciones de corte han sido evaluados mediante mapas de rigidez. El resultado muestra que la micromáquina provee suficiente rigidez para realizar operaciones de micromaquinado.application/pdfspaUniversidad Nacional de Colombia (Sede Medellín).
