The word ‘ceramic’ meant for
Determine the required cutting time T (s) for the workpiece made of steel (cutting speed V=400 m/min) external turning. Machined outer surface diameter d=323.5 mm and cutting length is 1497 mm. The feed during turning is s=2.5 (mm/rev) and the depth of cutting t=2.3 (mm), see figure below.
To calculate cutting time T (s) use following equation:T=l/(s·N),
where N - spindle rotational speed, rev/s; l - cutting length, mm.
Answer round up to two decimal places.
Find required spindle rotational speed N (rpm) for external turning of a workpiece made of steel. Outer radius of the workpiece is R=122.1 mm and cutting speed V=837 m/min.
Cutting speed for turning is calculated as:V=(π·D·N)/1000,
where D - workpiece diameter, mm; N - rotational speed, rev/min.
Answer provide as full number.
What is the type of cutting tool shown in figure below?
What is the type of cutting tool shown in figure below?
Calculate feed rate for the cutter shown below if the feed rate per tooth is 0.1 (mm) and the rotational speed N is 3055 (rev/min).
F=n·f·N,
where n - is amount of cutter's teeth.
Round up the answer to 1 decimal place.
What kind of chip occurs during brittle metal cutting?
Carbide-based cermets, i.e. carbide tools are used in cutting tools in a following manner:
Which turning operation and which surface of workpiece is possible to machine with the shown in the figure cutting tool?
