Quoteestimator

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:

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

Setup Time Estimates

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

Estimation Workflow

Step 1: Feasibility (Use PlantCapability)

• Can we make it?
• Which machine?
• Any showstoppers?

Step 2: Operation Breakdown

| Op# | Description | Machine | Setup | Cycle |
|-----|-------------|---------|-------|-------|
| 10 | | | min | min |
| 20 | | | min | min |
| 30 | | | min | min |

Step 3: Apply Factors

Base cycle time: X min
× Material factor (Y): X × Y = Z min
× 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: £____
Subtotal: £____
Margin (25-40%): £____
**Quote: £____**
