Si possono calcolare anche operazioni di foratura sul lato anteriore dei pezzi. Le lavorazioni simultanee sovrapposte, eseguite per esempio da più utensili o da torretta revolver, devono essere sovrapposte anche per via di calcolo, vale a dire che si devono aggiungere le forze di serraggio radiale necessarie delle singole lavorazioni.</p><p class="HText">Tuttavia i lavori di foratura e tornitura assiale si sovrappongono di rado, poiché normalmente non si svolgono in simultanea a causa dei sensi di rotazione opposti.</p><p class="HText">Per il calcolo, occorre basarsi sul punto con le forze più elevate, cioè il momento della lavorazione meno conveniente. In caso di dubbio, è necessario controllare diverse situazioni di taglio, per rilevare la meno conveniente.</p><p class="HText">Se si devono eseguire forature radiali, è fondamentale, oltre alla determinazione della forza di serraggio radiale  necessaria, soprattutto la verifica della forza trasversale  introdotta e del momento  che ne risulta.</p><p class="dlModulbegrenzung0"> </p><p

valori per il fattore di dispersione della forza di serraggio valgono solo nel caso di una regolare manutenzione e lubrificazione secondo le istruzioni per l'uso.</p><p class="HText">Se la forza di serraggio radiale viene misurata con un dispositivo di misura idoneo prima di ogni messa in servizio nonché costantemente ogni 100 serraggi, è possibile lavorare con il fattore di ampiezza di
