Final answer:
The chip-to-chip tool changing time is the time between a tool being removed from the spindle and the next tool being inserted in the spindle.
Step-by-step explanation:
The correct answer is option b) time between a tool is removed from spindle and next tool is inserted in spindle.
Chip-to-chip tool changing time refers to the time it takes for one tool to be removed from the spindle of a machine, and the next tool to be inserted into the same spindle. This process is important in industries that use machining tools, such as manufacturing or metalworking.
During chip-to-chip tool changing, the machine halts its operation so that the current tool can be safely removed and replaced with the next tool. This downtime is a significant factor in overall machining productivity and efficiency, as reducing the chip-to-chip tool changing time can lead to improved production rates.
