CNC Process Route Layout: Turn “First Plane, Then Hole, First Rough, Then Finish” into a Walkable Blueprint

I. Before Layout, Answer Three Questions

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.

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.
