Part Features: Long shaft, housing, or multi-face? → Determines machine type (Swiss-type, turn-mill, vertical, horizontal).
Accuracy Level: Roughing, semi-finishing, or mirror finish? → Determines process steps and machine grade.
Batch Rhythm: Single-piece or line flow? → Determines logistics form (straight line, circular, mixed flow).
II. Process Route Design Principles (On-Site Mnemonic) ① One-Time Datum: Forged surface is only for positioning; the first machined surface becomes the “mother datum” for all subsequent dimensions. ② Plane Before Hole: Machine planes first for stable positioning, then drill or bore to avoid hole position drift. ③ Rough Before Finish: Roughing releases heat and deformation; finishing is the final “light cut” shaping. ④ Same-Tool Concentration: Arrange same-tool processes consecutively to reduce tool change and repeated positioning. ⑤ No Interference: Previous process must not affect the next process’s positioning and clamping.
III. JSWAY Typical Layout Templates
Straight-Line Flow (Long Shaft) Equipment: Bar feeder → Swiss-type roughing → Turn-mill semi-finishing → Turn-mill finishing → On-line measurement Logistics: Bar stock runs through, no datum change, takt determined by feed speed.
Circular Flow (Housing) Equipment: Vertical machining center roughing → Turn-mill turning → 5-axis machining center finishing → CMM inspection Logistics: Robot loop handling, each machine does one process, balanced takt.
Mixed Flow (Multi-Variety Small Batch) Equipment: Vertical machining center (rough) → Turn-mill (semi + finish) → Grinding (mirror) Logistics: AGV + cloud scheduling, same line compatible with 3 part types, changeover in minutes.
IV. Process Division & Equipment Matching (JSWAY On-Site Version) • Roughing Island: High-torque vertical machining center or turn-mill, large tools fast stock removal. • Semi-Finishing Island: Swiss-type or turn-mill, corrects datum, leaves uniform allowance. • Finishing Island: High-precision turn-mill + grinding, micron-level removal, approaches final size. • Inspection Island: Laser interferometer + wireless ball-bar, on-line compensation, prevents error “flowing” to next machine.
V. Intelligent Optimization Tools • JSWAY Cloud Scheduling: Input part BOM and takt, auto outputs “process-equipment-logistics” matrix. • Digital Twin: Rehearses logistics and takt in virtual space, detects bottlenecks in advance. • Path Smart Optimization: Particle swarm algorithm adjusts tool path in real time, shortening air-cut distance.
VI. One-Sentence Summary Turn “one-time datum, plane before hole, rough before finish” into a walkable blueprint—let every process happen on the right machine, at the right takt, on the right logistics line. That’s the ultimate goal of JSWAY process route layout: right process, right time, right flow.
