PUMA205 Camshaft-Part Cell with Recirculating Chain Storage

The reference configuration has three PUMA205 lathes, one industrial robot and recirculating chain storage.

Technical application analysis. Camshaft components; three Doosan PUMA205 CNC lathes; six-axis robot and double-speed chain storage.

Reference configuration and timing

The reference configuration has three PUMA205 lathes, one industrial robot and recirculating chain storage.
It describes seven stations and capacity for 140 blanks. The stated 112 minutes of operation belongs to that source’s production assumptions.

Engineering evaluation

A recirculating carrier needs a process state as well as a physical position. Separate blanks, parts awaiting another operation and finished components so a returned carrier cannot restart the wrong operation.

Schedule the robot against each operation’s cutting time. Reorientation, chuck confirmation and temporary storage can become the constraint even when the storage capacity appears generous.

Selection conditions and evidence limits

The original 12 s handling and 48 s overall figures lack complete timing boundaries. Changeover, tool replacement and blank-datum variation must be evaluated before an output commitment.

Application questions

Does one robot serving three lathes guarantee balanced production?

No. Balance depends on operation times and the robot’s full service sequence, particularly simultaneous machine requests.

Can 140 storage positions define unattended duration?

Only with a verified parts-per-cycle rate, carrier usage and allowances for tools, chips and interruptions.
