quoteestimator

name	Quoteestimator
description	Rough cycle time and cost estimation for CNC machined parts. Uses MNMUK plant capabilities and standard estimating factors. USE WHEN user says 'quote', 'estimate', 'cycle time', 'how long', 'cost estimate', 'pricing', 'how much to make', or describes a part needing a rough quote.

QuoteEstimator - MNMUK Quoting Support

Purpose: Rapid rough-order-of-magnitude estimates for quoting. Not a replacement for proper process planning, but gets you in the ballpark fast.

When to Activate

• "How long to make this part?"
• "Rough quote for [part description]"
• "Estimate cycle time for..."
• "What would it cost to make 500 of these?"
• "Quick estimate for quoting"

Disclaimer

These are rough estimates for quoting purposes. Actual times depend on:

• Specific geometry complexity
• Tolerance requirements
• Surface finish specs
• Fixturing approach
• Tooling availability
• Operator experience

Always add contingency and verify with experienced estimator for critical quotes.

Cycle Time Estimation

Turning Operations

OD Turning

Time (min) = (Length × Passes × π × Diameter) / (Feed × Speed × 1000)

Simplified:
Rough: Volume removed (cm³) × 0.5 min/cm³
Finish: Surface area (cm²) × 0.02 min/cm²

Quick Estimates - OD Turning:

Part Size	Rough	Finish	Total
Ø25 × 50mm	0.5 min	0.3 min	0.8 min
Ø50 × 100mm	2 min	1 min	3 min
Ø100 × 150mm	6 min	2.5 min	8.5 min
Ø150 × 200mm	12 min	4 min	16 min

ID Boring

Multiply OD time × 1.5 (slower, less rigid)
Deep bores (L/D > 4): × 2.0

Threading

Single-point: 0.3 min per 25mm thread length (standard pitch)
Thread milling: 0.5 min per thread
Tapping: 0.1 min per hole (standard)

Grooving/Parting

Grooving: 0.2 min per groove
Part-off: Diameter (mm) × 0.01 min

Milling Operations

Face Milling

Time = (Area / (Width of Cut × Feed Rate)) + Approach

Quick: Area (cm²) × 0.02 min/cm² for roughing
       Area (cm²) × 0.01 min/cm² for finishing

Pocket Milling

Volume (cm³) × 0.8 min/cm³ (aluminium)
Volume (cm³) × 1.5 min/cm³ (steel)
Volume (cm³) × 3.0 min/cm³ (stainless/titanium)

Add 50% for finishing passes

Drilling

Standard drill: Depth (mm) × 0.02 min/mm
Peck drilling: Depth (mm) × 0.04 min/mm
Deep hole (>5xD): Depth (mm) × 0.08 min/mm

5-Axis Contouring

Surface area (cm²) × 0.15 min/cm² (aluminium)
Surface area (cm²) × 0.3 min/cm² (steel)
Surface area (cm²) × 0.5 min/cm² (titanium)

Complex surfaces: Add 50-100%

Swiss Operations

Small precision parts (Ø3-10mm):
- Simple: 30-60 sec/part
- Standard: 60-120 sec/part
- Complex: 120-300 sec/part

Medium parts (Ø10-25mm):
- Simple: 60-120 sec/part
- Standard: 120-240 sec/part
- Complex: 240-480 sec/part

EDM Operations

Wire EDM

Cut length (mm) × thickness (mm) × 0.003 min/mm² (roughing)
Add 50% per skim pass (typically 2-4 skim passes)

Example: 100mm perimeter × 25mm thick
- Rough: 100 × 25 × 0.003 = 7.5 min
- 3 skims: 7.5 × 1.5 × 1.5 × 1.5 = 25 min total

Spark EDM

Volume to remove (cm³) × 30-60 min/cm³
Roughing faster, finishing much slower
Electrode making: Add 1-4 hours depending on complexity

Quick Quote Formula

Total Cost = (Setup Cost) + (Run Cost × Quantity) + (Material Cost) + (Secondary Ops)

Where:
- Setup Cost = Setup Time × Hourly Rate
- Run Cost = Cycle Time × Hourly Rate × Material Factor × Tolerance Factor
- Material Cost = Weight × £/kg × Waste Factor (typically 1.3-1.5)
- Secondary Ops = Finishing, heat treat, plating, inspection (get quotes)

Quantity Breaks

Quantity	Multiplier	Notes
1-5	1.5	Prototype pricing
6-25	1.2	Small batch
26-100	1.0	Standard
101-500	0.9	Efficiency gains
500+	0.8	Volume pricing

× Tolerance factor (T): Z × T = A min
× Complexity factor (C): A × C = B min
Adjusted cycle time: B min

Step 4: Calculate Costs

Setup: [time] × £[rate] = £____
Run: [cycle] × [qty] × £[rate/60] = £____
Material: [weight] × £[per kg] × 1.3 = £____
Secondary: £____
