In one aspect the invention relates to a control unit (100) for providing control instructions (ci) for controlling a laser cutting machine (L) by determining transition phases for transforming different dynamic laser beam shapes for the laser cutting machine (L), preferably comprising a dynamic laser beam shaping module (DBSM) for dynamically varying the shape of the laser beam. The control unit (100) comprises: A cutting plan interface (101) for receiving a cutting plan to be processed for cutting out parts of a workpiece, wherein each part is defined by a cutting contour consisting of cutting segments, which are ordered in a queue; An allocation tool (102), which is configured to allocate a specific dynamic laser beam shape from a set of dynamic laser beam shapes to each cutting segment in the queue of cutting segments according to predefined assessment criteria; A transition tool (104) for determining transition phases between each two consecutive specific dynamic laser beam shapes, wherein a first specific dynamic laser beam shape of the two consecutive specific dynamic laser beam shapes is transformed into a second specific dynamic laser beam shape of the two consecutive specific dynamic laser beam shapes within a transition time (t); A processor (P), which is configured for accessing the allocation tool (102) iteratively for determining a specific dynamic laser beam shape for each cutting segment of the queue of cutting segments and wherein the processor (P) is further configured for accessing the transition tool (104) for determining all transition phases between each two consecutive specific dynamic laser beam shapes and wherein the processor (P) is configured for providing control instructions (ci) for controlling the laser cutting machine (L) for executing the received cutting plan by applying: 1. the specific dynamic laser beam shape, determined by the allocation tool (102), and 2. the transition phases between each two consecutive specific dynamic laser beam shapes, being determined by the transition tool (104). Dans un aspect, l'invention se rapporte à une unité de commande (100) servant à fournir des instructions de commande (ci) pour commander une machine de découpe au laser (L) en déterminant des phases de transition pour transformer différentes formes de faisceau laser dynamique de la machine de découpe au laser (L), comprenant de préférence un module de mise en forme de faisceau laser dynamique (DBSM) servant à faire varier dynamiquement
