Variants change, deadlines press, and disruptions tear gaps in the takt. If you want to optimize your assembly process, you need a clean analysis and fast validation. This is where VR connects planning and practice: you see routes, postures, and bottlenecks, compare variants, and decide based on numbers. Halocline, the planning platform for production layouts and workstations, supports you pragmatically, from the 3D layout to the walkthrough in VR or on the desktop.
It starts with a clear target picture and a reliable data basis. In assembly, takt time, lead time, quality, and ergonomics matter most. Typical forms of waste work against them: long routes, searching, far or high grips, and changeover losses. In VR, you make these effects visible before anything is physically rebuilt. This lets you test changes while they only cost a few mouse clicks, and lowers risk and rebuild costs.
In collaboration, industrial engineering (IE) and methods planning provide the time data and line balancing. Assembly contributes its practical knowledge of grips and reach, lean moderates waste and standards, and planning is responsible for the shopfloor layout and material flow. With Halocline, you bring this together in short sessions: open the model, go through the variants, save the measured values, decide.
Metrics set direction and pace. Takt time is derived from demand and available time, and no station time may exceed it. A worked example: 27,000 s of shift time and 450 units result in a takt of 60 s. If a station needs 68 s, the flow backs up until you redistribute work or shorten routes.
A loss analysis shows where the biggest levers are: disruptions, changeover times, and quality defects. Suppose the analysis shows 12 % loss from searching for material, 8 % from changeovers, and 3 % from rework: then the order of measures is clear.
You measure operator routes in meters or steps per cycle. A starting value of 14 m per cycle adds up to 6.3 km over 450 cycles per shift. If you arrange material closer and check the grasping path in VR, the distance drops to 11 m per cycle. That's 21 % less, noticeable in both time and strain. In addition, you document grip heights and distances for the main grips. As a rough guide for frequent grips, about 80 to 120 cm in height and up to 45 cm in distance apply; the grasping area avatars in Halocline show it more precisely for gender and body height. You spot deviations in VR right away, as well as blocked lines of sight, and the collision check reveals conflicts in the layout.
You manage quality through the defect rate and first pass yield (FPY). An FPY of 92 % means that 8 out of 100 units don't pass error-free the first time. The causes often lie in unfavorable grasping paths, poor visibility, or the risk of mix-ups. In VR, you check labeling, poka-yoke guides, and grasping logic directly on the workstation model. Rebuild and change costs round off the decision: if a variant delivers equivalent times in VR but requires significantly fewer rebuilds, that's a clear advantage.
In the virtual factory, you test layouts and workstations at 1:1 scale before you invest. With Halocline, you build 3D layouts from the library with no training required and without CAD data, place material, check grasping areas with grasping area avatars, and walk through the station in VR. One person wears the headset while the others follow the walkthrough in spectator mode on screen. You create variants as copies and switch between them to compare. The recording adds routes and times, so you spot bottlenecks, narrow aisles, and unfavorable heights early and back them up with numbers.
You achieve even utilization when no station time exceeds the takt and routes stay short. A scenario: station 3 is at 68 s, station 4 at 52 s, and the takt at 60 s. You move labeling (8 s) to station 4 and shorten two grips from 70 to 35 cm, which saves another 2 s. Station 3 then runs at 58 s, station 4 at 60 s, and the flow stabilizes.
A layout comparison is worthwhile in parallel: a line with four stations versus a U-cell. In the recording, the U-cell comes to 11 m instead of 14 m per cycle, around 20 % less walking. Over 450 cycles per shift, the distance drops from 6.3 km to just under 5.0 km. This relieves the workforce, reduces search times, and smooths out non-value-adding times.
Ergonomic risks cost performance and quality. Typical ones are overhead work, twisted postures, and long reach distances. In VR, you measure grip heights and distances with the measuring tool, assess back and shoulder posture with your own body, and document the target state. If you record the workflow, the ergonomics analysis based on the key indicator method marks problematic object movements in yellow or red.
A scenario: a screwing task sits above shoulder height. The component is lowered by 400 mm, and the screwing point drops from 1,600 to 1,200 mm. Overhead work disappears, reach distances stay within the target range of up to 45 cm, and steadier hand guidance reduces errors. You apply changes such as "rotate the rack, move the workstation by 200 mm, route the milk run on the left" directly in the model and walk through them again right away, without waiting for CAD designs. At Siemens in Karlsruhe, workstation design with Halocline became 4x faster.
For a pragmatic start, the five-step sequence above is enough: set target values, capture the current state, identify the bottleneck, compare variants in VR, and then plan the rebuilds in a targeted way.
