Question

We have a rectangular piece. We wish to manufacture a parallel slot along thepiece in a vertical milling machine and 50 cm from the edge. The width of the slot is 40 mm. TheDepth of the slot is 25 mm. For this, several rough cutting steps and aFine cut with a depth of 0.20 mm. The depth for each of the steps ofrough cut is limited to 1.75 mmAditional information:

Cost Information: Rectangular Piece Information $40/hr $2.50 1.5 min 10 min/piece 2.9 GJ/mA3 Operation and machinary Blade Blade change Time Non-productive time Specific Power Dimentions Length Width Hight 100 cm 250 cm 65 cm Machine information: Blade Information: Material Diameter Number of teeth Taylors Index Taylors Constant Carbide 25mm 8 0.25 500 for velocity (m/min) Engine Power (Pe) Efficiency 80% Fine-cut Information: 0.03mm/tooth Rough-cut Information It is done so that the production time is minimum 0.1 mm/tooth It is held to maximum power

What is the number of blades used for the rough cutting steps?What is the number of blades used for the fine cutting step?
