Application Example 1
Before TRAK 2op
— Total man hours: 20.6/lot
Parts are processed through a cell consisting of two turning centers that are run simultaneously by one operator. One turning center performs the 1st operation while the other performs the 2nd operation. Once the entire lot is processed through the cell, it is moved 30 feet to the machining center to complete the 3rd operation by a second operator.

![A second operator is necessary since the third operation is a full 30 feet away from first and second operations. TRAK 2op Application Example 1, Figure 2](/assets/images/articles/2019-06-04-2op-application-example-1-figure-2.jpg?r=2)
After TRAK 2op
— Total man hours: 12.5/lot
Parts are run through a cell consisting of two turning centers and the portable TRAK 2op VMC. All three machines are run simultaneously by the same operator — one turning center performs the 1st operation, the other turning center performs the 2nd operation, and the TRAK 2op performs the 3rd operation.
![With the TRAK 2op in place, all operations can be managed by a single operator. TRAK 2op Application Example 1, Figure 3](/assets/images/articles/2019-06-04-2op-application-example-1-figure-3.jpg?r=3)

Example 1 Results
Before TRAK 2op | After TRAK 2op | |
---|---|---|
Lot Size | 150 pieces | 150 pieces |
1st Operation Cycle Time (turn one side) | 2.25 minutes | 2.25 minutes |
2nd Operation Cycle Time (turn oposite side) | 5 minutes | 5 minutes |
3rd Operation Cycle Time (mill, center drill, drill) | 3.25 minutes | 4.25 minutes |
Total Man Minutes | (5 + 3.25)*150 = 1,237 minutes or 20.6 hours |
5*150 = 750 minutes or 12.5 hours |
Application Example 2
Before TRAK 2op
— Total man hours: 22.5/lot
Parts are machined “three up” on the machining center in operation sequence (operations 1, 2, and 3). The machine is run by one operator.
![All operations occurring in sequence using a machining center. TRAK 2op Application Example 2, Figure 1](/assets/images/articles/2019-06-04-2op-application-example-2-figure-1.jpg?r=2)
After TRAK 2op
— Total man hours: 13.8/lot
Parts are machined “two up” on the machining center in operation sequence (operations 1 and 2). The portable TRAK 2op is placed next to the machining center and simultaneously performs the 3rd operation. One operator runs both machines.
![The same operator can now run the machining center and the TRAK 2op simultaneously thereby reducing idle time. TRAK 2op Application Example 2, Figure 2](/assets/images/articles/2019-06-04-2op-application-example-2-figure-2.jpg?r=4)

Example 2 Results
Before TRAK 2op | After TRAK 2op | |
---|---|---|
Lot Size | 150 pieces | 150 pieces |
1st, 2nd and 3rd Operation Cycle Time (face mill, center drill, drill, mill, tap) | 9 minutes | n/a |
1st and 2nd Operation Cycle Time (face mill, center drill, drill, tap) | n/a | 5.5 minutes |
3rd Operation Cycle Time (mill, center drill, drill, tap) | n/a | 4 minutes |
Total Man Minutes | 9 *150 = 1350 minutes or 22.5 hours |
5.5*150 = 825 minutes or 13.8 hours |
The TRAK 2op was designed to increase the productivity of multi-operations machining. It can be moved easily and quickly to meet the needs of constantly changing job requirements, and can be deployed in nearly limitless work cell configurations.
