Problems solved by technology

[0011] However, the airbag tear line forming apparatus 200 described in Patent Document 1 is not equipped with a recovery device for waste generated by the cutting process, and no consideration is given to the waste remaining on the tear line.
That is, when the depth of the tear line (fracture groove) is measured using an optical measuring device such as a laser displacement meter, there is a problem that it is difficult to accurately measure the depth of the tear line because the waste interferes with the measurement accuracy.
In particular, it is difficult to measure the depth of the tear line quickly and with high precision at the same time due to the influence of a large amount of waste generated during the cutting process, and to feed back this value to adjust the cutting state
[0012] In addition, the airbag tear line forming device 200 described in Patent Document 1 is provided with a solenoid 208 for reciprocating a cutting tool for a predetermined distance (about 0.5 to 3 mm). The time required to form the linear cut portion becomes longer, so there is a problem that the manufacturing cost increases
[0013] In addition, although the dust collector 501 described in Patent Document 2 intends to recover the dust generated by the hammer body 510b as a machining device, it does not take into account the prescribed antistatic treatment, so even if a cyclone and a recovery tank are installed Etc., static electricity will also be generated so that the dust cannot be recovered efficiently
[0014] Especially in the dry period of winter, a large amount of dust generated is electrostatically attached to the inner walls of cyclones, recovery tanks, etc., making it difficult to efficiently discharge to the outside
[0015] In addition, the cylindrical cover portion 502 surrounding the weight body 510b has rubber bellows portions 502b, 502d as a whole, and is easily elastically deformed not only in the vertical direction but also in the lateral direction, so it is easy to contact the weight body 510b, and as a result, there may be Difficulty in machining with high precision
[0016] In addition, although the mechanical processing device equipped with a waste recovery device described in Patent Document 3 has excellent recovery efficiency of waste of a predetermined size, it does not consider the influence of Joule heat on machine tools in a predetermined environment.
[0017] Therefore, there is a problem that the machine tool is easily deteriorated for a long period of time and in the case where the machining device is driven at high speed at an ambient temperature exceeding 40° C. or, more remarkably, at a temperature exceeding 50° C.
[0018] In addition, if the machine tool deteriorates, there is a problem that the processing accuracy of the workpiece will be significantly reduced.
[0019] In addition, fine particles with an average particle diameter of less than 100 μm or more significantly less than 0.1 to 10 μm tend to remain on the workpiece depending on the type of machining, and become an important factor for measurement errors related to the processing depth.
