DYNAMIC TOOL ABRASION CORRECTION METHOD IN NC MACHINE TOOL |
摘要 |
A method of the invention detects a machining load acting on a tool during a machining process, estimates abrasion amount of the tool based on the machining load and a tool abrasion characteristic registered in advance in a memory, and changes automatically tool position compensation amount based on the tool abrasion. The estimating computation of tool abrasion amount is performed by, for example, obtaining in advance a tool abrasion coefficient based on tool abrasion amount per unit time when a main spindle load current value is taken as a reference machining current value, and integrating for a machining time the product of a ratio of a main spindle load current value during an actual machining process to the reference current value and said tool abrasion coefficient. |
