   Theory. Cutting speed is the relative linear velocity between the cutting edge and the workpiece. At each point, the cutting speed is the product of the rotation speed of the drill (Spindle speed) and the circumference. In the drill’s center, the cutting speed is always zero, and it increases gradually as you get further away from the center.

   In physics, power is defined as the amount of energy transferred per unit of time. In the case of CNC machining, the electrical network passes energy to the spindle’s electric motor, which passes it to the cutting tool. The cutting tool uses this energy to extract material from a workpiece. Assuming the efficiency is 100%, the power required to rem...

   In mechanics, the power of a motor is the product of the torque and the shaft’s angular velocity. In machining, this translates to the Torque acting on the spindle multiplied by the spindle speed: The problem is that calculating the cutting force is a rather complex computation that cannot be summarized into simple formulas. Luckily, there is a wor...

   How to cut stone with wedges & shims?

   • Cutting stone with wedges and shims (also know as V cutting) is the traditional method for splitting blocks of stone in a simple way. The objective is to obtain different volumes with the flattest sides possible. The most important thing when using this method is to follow the grain of the stone that you’re cutting.

   What is specific cutting force?

   • Specific Cutting Force (KC): A material property that indicates the required force needed to extract a chip out of the workpiece. Material charts on the web (or in catalogs) list the KC value per raw material or material group. (Learn more about Specific Cutting Force ) Calculating the cutting power requires 4 steps:

   How to calculate cutting power?

   • Calculating the cutting power requires 4 steps: Material removal rate (MRR) is the volume of material removed per time unit during machining operations such as milling, turning, drilling, and grooving. It is designated by the letter Q and measured in cubic Inches per minute or cubic centimeters per minute.

   How do you break a stone?

   • Once you’ve made the holes, place the wedges and shims inside with the ears pointing in the direction of the fracture line, and then strike each one successively (strike the first one, then the second, and continue like this until you’ve hit them all, then start over). Keep doing this until the stone eventually opens up down the middle.

   How do you split a stone with a wedge?

   • To do this, first you’ll need to make holes in the stone, then use the wedges in combination with two steel shims with sharp edges, which will help the wedge to split the stone apart. The size of the wedges and shims you use will depend on the size of the stone that you’re splitting.
