THE “PREP-BOT” CELL
The current manufacturing process of getting a blank tool ready for the cutter grinder involves numerous operations and high employee involvement. Automating the machines and incorporating a 6 axis robot allows for unattended operations and frees up the operator to complete other essential tasks.

The Cell Process
A centrally located robot eliminates the need for individual operators to be present at each machine. The cell functions autonomously with the robot transitioning the blanks to each station on a set schedule.
The robot has 2 independent encompassing grippers to move the blanks to each station. One gripper removes the processed blank and the other gripper inserts a new blank into the station.
Once the system is fully loaded (wet), there will be 4 blanks in process: (1) getting cut to length in the Cut-Off Machine, (1) getting chamfered in the Chamfer Machine, (1) getting measured/verified in the OD Laser Micrometers, (1) getting etched in the Laser Marking System. *1.
The ultimate goal is to have one completely processed tool placed into the outgoing pallet, located on the conveyor system, within the cycle time of the Cut-Off machine. Therefore, the robot has to transition a new blank into the subsequent stations, those stations are required to process and complete the new blank prior to another blank coming off the Cut-Off Machine.
The cycle time of the Cut-Off Machine is dependent on the rod (blank) diameter. A larger rod diameter results in a longer cycle time and a smaller diameter has a shorter cycle time.
Once the outgoing tray/pallet is fully loaded (i.e. a standard batch size) with processed blanks, the conveyor system moves the pallet to a designated area for the cutter grinder and a new empty pallet automatically moves to the robot loading area.
The operator is in total control, but ultimately responsible for initially inputting the parameters into each machine/station, loading the Cut-Off Machine, loading/unloading pallets from the conveyor system and ensuring that the overall cell is working efficiently.
