Machine tending In and out, one loop

The robot pauses at the door, goes straight in to set the blank in the chuck, and comes back out the same way. It keeps machines running through the night.

Machine tending process path plate: the tool path traced many times over (in and out, one loop). The open circle marks the start, the filled dot the end.

Process sequence

One path, five steps.

Scroll down and each step lights up in copper on the plate.

Machine tending sequence, plan view: the same cell seen from above. The numbers match the steps.
  1. 1. Pick the blank

    A camera locates the blank in the tray and the robot picks it.

  2. 2. Wait at the door

    When the cycle ends and the door opens, the robot gets the signal and moves in.

  3. 3. Swap

    A dual gripper pulls the finished part and sets the blank in the chuck.

  4. 4. Cycle start

    Once the robot is clear, the door closes and machining starts.

  5. 5. Blow off and stack

    Chips and coolant are blown off the finished part before it goes into the tray.

Design points

Designing the cell: three things first.

  1. 1. Dual grippers

    Unload and load in a single visit. That keeps the door-open time short.

  2. 2. Handshake with the machine

    Door open, cycle complete, and chuck open/close signals pass between the HGC-7 and the machine PLC. We verify the machine-side wiring with you before commissioning.

  3. 3. Slows down when people approach

    Area scanners slow or stop the robot when someone approaches. Speeds and distances come from the risk assessment.

Recommended robots

Our first pick for this job.

Machine tending is about keeping spindles turning. While a person loads and unloads, the machine waits, and when the shift ends, the machine stops too. With a robot on the job, the machines keep cutting through the night until the planned quantity is done.

Place an HG-C10-13 cobot between two facing CNC machines and one robot runs both. Blanks and finished parts sit in drawer-style trays, and operators only swap the trays.

When machines are spread across the floor, the HG-M600C mobile manipulator makes the rounds. For heavy blanks, use the HG-R25-18 or HG-R210-27.
