Workpiece. Workpiece. Chip. ECE. Ff f fi c i ci on cutting forces had been observed, it should be mentioned.

Two sets of factors are the condition of work-piece materials and the physical properties of work-piece materials. The condition of the work-piece material includes eight factors: microstructure, grain size, heat treatment, chemical composition, fabrication, hardness, yield strength, and tensile strength.

In addition to the material, the specific cutting force is also influenced by the chip angle. For example, there is a rule of thumb that for every degree that the cutting edge becomes more positive, 1.5 percent less force is required to form a chip. This rule of thumb is instinctively supported, as a sharp knife cuts easier.

It allows you to effectively process a high-quality blank for thick and medium sheet metals. Plasma arc cutting is ideal for the automation of the cutting process. When plasma arc cutting underwater - it creates a very low level of noise and produces a very low heat exposure too. Image of Plasma Cutting torch.

In machining, the material of the workpiece used should be taken into account in order to predict the forces and reactions that the cutting operation will 

Cutting speed, also known as surface speed, refers to the speed at the outside edge of the tool as it is cutting. It is measured in surface feet per minute (SFM). Cutting speed is mainly depending on the type of materials and cutting tools, related to their hardness. The harder the material, the slower the cutting speed should be.

lm (mm): Length of workpiece. l (mm/min): Machined length per minute. memo. This formula is used to calculate the machining time from the length of the workpiece and the spindle speed. Example: Feed (f) = 0.2 mm/rev. Spindle speed (n) = 1100 min -1. Length of workpiece (lm) = 120 mm. First, the machined length per minute is calculated, in this

specific cutting force coefficients and cutting forces of the composite were estimated using C45 carbon steel as the workpiece material.

The increase in force has an impact on the workload and tool life of the Workpiece-Fixture-Machine Tool-Cutting Tool (WFMC) system. Therefore, in applying the Kienzle and Viktor relationship to calculation of the cutting force, we need to know the change in the specific cutting force (kc1.1) and the exponent related to it (z) in cases where a

composite workpieces material. Cutting force is one of the cutting conditions that can determine the machinability of the workpiece.

The cutting force signal is simulated for the location of the cutter with respect to the workpiece shown in Fig. 5. This location of the cutter and workpiece corresponds to four pairs of entry–exit angles. The cutting force signal was simulated based on the multiple insert specific cutting pressure constants from Table 6.
