9. Recommended Cutting Conditions

Optimized cutting parameters for the CPMT090304GP CA525 when machining carbon and alloy steels:

Operation	Cutting Speed Vc (m/min)	Feed Rate fn (mm/rev)	Depth of Cut ap (mm)
Roughing	160-220	0.15-0.30	1.0-3.0
Finishing	220-300	0.05-0.12	0.2-1.0

Note: Values are guidelines for stable conditions with adequate coolant supply. Reduce speeds by 15-20% for alloy steels and 25-30% for stainless steels. Always perform test cuts to optimize for your specific machine and setup.

10. Operating Guidelines

Coolant Recommendation: High-pressure water-soluble coolant (5-8% concentration) or neat cutting oil for finishing operations
Entry Strategy: Use ramp entry or arc entry to avoid impact loading on the insert edge
Tool Overhang: Minimize tool overhang to ≤ 1.5x holder height to reduce vibration and improve stability
Insert Seating: Ensure clean insert pocket and proper seating torque (2.5-3.5 N·m for M2.5 screws, 3.5-4.5 N·m for M3.5 screws)
Chip Management: Verify chip flow direction; use chip deflectors if necessary to protect the workpiece surface
Speed Ramp-Up: Start at 70% of recommended Vc and increase gradually while monitoring tool wear and surface finish
Tool Life Check: Monitor flank wear (VB). Replace insert when VB reaches 0.3mm for roughing or 0.15mm for finishing
Storage: Store inserts in original packaging away from direct moisture and temperature extremes

11. Toolholder Compatibility

The CPMT090304GP is a positive-style insert requiring compatible positive toolholders. Recommended holder configurations:

Holder Type	Compatible Models	Shank Size
