Processing & Inspection Machine List.pdf
The gear processing process generally goes through the following stages: blank heat treatment, tooth blank processing, tooth profile processing, tooth end processing, tooth surface heat treatment, fine reference correction and tooth profile finishing.
The first stage of processing is the stage when the gear blank initially enters machining. Since the transmission accuracy of the gear is mainly determined by the tooth shape accuracy and the uniformity of the tooth pitch distribution, which is directly related to the accuracy of the positioning reference (hole and end face) used in gear cutting, this stage is mainly for the next stage of processing The tooth shape is prepared with a fine reference, so that the precision of the inner hole and end face of the tooth basically meets the specified technical requirements. In this stage, in addition to processing the datum, the processing of the secondary surface other than the tooth shape should also be completed in the later stage of this stage as much as possible.
The second stage is the machining of the tooth profile. For gears
that do not need to be quenched, generally speaking, this stage is
the final processing stage of the gear. After this stage, the gear
that fully meets the requirements of the drawing should be
processed. For gears that need to be hardened, it is necessary to
process the tooth shape accuracy required by the final finishing of
the tooth shape at this stage, so the processing at this stage is
the key stage to ensure the machining accuracy of the gear. Special
attention should be given.
The third stage of processing is the heat treatment stage. In this stage, the tooth surface is mainly quenched to make the tooth surface meet the specified hardness requirements.
The final stage of machining is the finishing stage of the tooth profile. The purpose of this stage is to correct the tooth shape deformation caused by the gear after quenching, further improve the tooth shape accuracy and reduce the surface roughness, so that it can meet the final precision requirements. In this stage, the positioning datum surface (hole and end face) should be trimmed first, because the inner hole and end face of the gear will be deformed after quenching. If such a hole and end face are directly used as a reference for tooth profile finishing after quenching, It is difficult to meet the requirements of gear precision. Finishing the tooth shape with the trimmed datum plane positioning can make the positioning accurate and reliable, and the margin distribution is relatively uniform, so as to achieve the purpose of finishing.

FAQ:
Q1: What is a turning insert?
A: W - trigon 80° C and W type turning inserts are often used for rough machining due to their larger point. angle, which makes them more rigid. Inserts with a smaller point angle, such as D and V, are often used for finish machining.
Q2: Which type of surface is produced in turning operation?
A: Turning is a process of removing excess material from the work-piece to produce an axisymmetric surface, in which the work-piece rotates in a spindle and the tool moves in a plane perpendicular to the surface velocity of the job at the tool-job contact point.
Q3: What is the difference between turning and knurling?
A: Straight knurling is often used to increase the workpiece diameter when a press fit is required between two parts.
Q4: What is spindle speed?
A: The spindle speed is the rotational frequency of the spindle of the machine, measured in revolutions per minute (RPM). The preferred speed is determined by working backward from the desired surface speed (sfm or m/min) and incorporating the diameter (of workpiece or cutter).
Q5: What is depth of cut in turning?
A: It is the total amount of metal removed per pass of the cutting
tool. It is expressed in mm. It can vary and depending upon the
type of tool and work material. Mathematically, it is half of
difference of diameters. Depth of cut (t) = D-d/2 mm.
Q6: What is turning milling and drilling?
A: Turning operations are operations that rotate the workpiece as the primary method of moving metal against the cutting tool. Lathes are the principal machine tool used in turning. Milling operations are operations in which the cutting tool rotates to bring cutting edges to bear against the workpiece.
