Problems solved by technology
[0002] At present, when a cylindrical workpiece, such as a straight pipe with a spiral band on the outer circle of a straight pipe, needs to be processed, since the width of the spiral band on the outer circle of the straight pipe is constant, the distance between adjacent spiral bands changes with the change of its radial height dimension, resulting in The calculation of the coordinate points on the side is complicated and difficult to calculate manually, so only computer-aided programming can be used
Although this can meet the needs of processing, it is necessary to build a 3D model of the workpiece before processing, and then use computer-aided programming software for programming. The programming process is cumbersome and inconvenient, and it must be equipped with computer-aided programming software to implement, and the scope of application is limited.

Embodiment
[0039] Such as figure 1 , figure 2 , image 3 As shown, according to the method of the present invention, the straight steel pipe workpiece whose material is SA-312TP316H is processed on the outer circle with the groove between the spiral bands:
[0040] S1. Take the straight steel pipe workpiece to be processed, measure the outer circle radius R=300mm of the straight steel pipe workpiece to be processed; according to the design requirements, determine the width of the spiral strip to be processed b=40mm, the height of the spiral strip to be processed H=30mm, and the spiral strip to be processed The fillet at the bottom of the belt is r=5mm, the angle between the centerlines of the adjacent helical belts to be processed is θ=18°, and the rising angle of the helical belts is α=45°.
[0041] S2. Determine the number of milling layers of the spiral groove: take the milling depth a of each layer p =1.9, take the bottom finishing allowance e 2 = 1.5; then,
[0042] S3, rand...

The invention relates to a mechanical processing technology, and specifically discloses a method for processing grooves between spiral bands on the outer circle of a cylindrical workpiece. This method realizes the parametric numerical control programming of the grooves to be processed between adjacent spiral strips by first obtaining the distance between adjacent spiral strips, which can replace the use of computer-aided programming to process the spiral strips on the outer circle of cylindrical workpieces; parametric programming does not require Establish a three-dimensional model of the workpiece, so it makes the NC programming process more convenient and efficient on the premise of ensuring the accuracy and reliability of the NC programming, and is beneficial to shorten the workpiece processing preparation cycle; relatively speaking, parametric programming has relatively low skill requirements for NC programmers. low, which is conducive to wide application.
Description
technical field [0001] The invention relates to a mechanical processing technology, in particular to a cylindrical workpiece processing technology. Background technique [0002] At present, when a cylindrical workpiece, such as a straight pipe with a spiral band on the outer circle, needs to be processed, since the width of the spiral band on the outer circle of the straight tube is constant, the distance between adjacent spiral bands changes with the change of its radial height, resulting in The calculation of coordinate points on the side is complicated and difficult to calculate manually, so only computer-aided programming can be used. Although this can meet the needs of processing, it is necessary to build a three-dimensional model of the workpiece before processing, and then use computer-aided programming software for programming. The programming process is cumbersome and inconvenient, and it must be equipped with computer-aided programming software to implement it. The...
