Process of mechanical technology machining

Machining process is in manufacturing process, those and raw material change calls process for the process with direct and relevant product. It includes semifinished product to make, spare parts treatment, heat treatment, quality inspection and machine are assembled etc. And the cutting tool that needs to assure place of process on the rails, clamping apparatus is made, the machine tool adjusts maintenance to wait to belong to auxiliary process. In process, press certain order to change semifinished product appearance, dimension, relative position and function stage by stage to wait with machining method, till make that part process of eligible spare parts,call machining process. Technical personnel is mixed according to condition of product measure, equipment the circumstance such as worker quality, decide adoption process, keep concerned content into craft file, this kind of file weighs procedure. To facilitate the work out of procedure, carry out and produce constituent government, need differentiates process the unit that is disparate arrangement of ideas. They are working procedure, installation, labour, labor situation and take a knife. Among them working procedure is the main unit in process. The machining process of the spare parts by a certain number of working procedure composition. In the likelihood in a working procedure the bag contains or a few are installed, each installation may include or a few are versed in, each labour the likelihood includes or be versed in a few times pace, each labor situation may include or a few take a knife. (1) working procedure or a group of workers, the process of that one part that one is opposite on ground of a job or a machine tool or completes continuously to a few workpiece at the same time calls working procedure. Delimit the basis of foreword of division of labor is workplace whether change and working process is successive. For example, a batch of rods are processed on lathe, can have rough machining and precision work continuously to each axis already, also can be opposite first whole batch the axis undertakes rough machining, next again ordinal have precision work to them. Below the first kind of case, treatment includes a process only; And fall in the 2nd kind of case, as a result of treatment process successional interrupt, although treatment has on same table machine tool, but make two process however. Working procedure is the main unit that forms process, also be the main unit that produces a plan. (2) installation is in machining working procedure, make workpiece is in machine tool go up or some is held in clamping apparatus proper place and by the process of clamp, call outfit clip. Sometimes, workpiece needs to finish the working content of a working procedure through installing clip ability for many times on the machine tool. Installation is that part process that after showing workpiece passes outfit clip, completes content. For example, the rod is processed on lathe, give partial appearance from treatment of one aspect of the matter first, next tune rework other one aspect of the matter, at this moment working procedure content includes two installation. (3) labour use dislocation (or shift) workbench of clamping apparatus, circumgyrate or be in on much axis machine tool when treatment, workpiece installs clip hind last time in the machine tool, should pass a certain number of the position is ordinal undertake machining, process of each when workpiece holds on the machine tool that one part that completes locally calls project. Simple for, workpiece is opposite the content of that part process that at machine tool or cutting tool every hold place of position of a treatment to finish, call project. The outfit that be placed to because be installed for many times,decrease and brings places loss of time of sum of errors, often use clamping apparatus of all sorts of circumgyrate workbench, circumgyrate or mobile clamping apparatus, in making workpiece holds clip in, be in a few different positions to undertake machining early or late. Graph 1-1 is in a 3 labour the sketch map that bearing machines to cover bolt hole on circumgyrate workbench machine tool. Handlers is versed in in fluctuation makings a workpiece of Ⅰ place mount, when this workpiece ordinal be versed in through bore a Ⅱ , reaming is versed in a Ⅲ hind, clip hind can be installed to end aperture of 4 a flight of stairs in two positions treatment in. Such, decreased to hold clip number already, be versed in because of each again treatment and assembling and unassemble undertake at the same time, thereby managing installation time makes productivity can rise greatly. The 3 labour of aperture of bolt of lid of graph 1-1 bearing treatment (4) labor situation is machining the surface changeless, below the condition with treatment changeless tool, the content of process of that one part that place finishs continuously calls labor situation. “ feed ” often also is called in production. Whole process by a certain number of working procedure composition. Each working procedure can include situation of a labor or situation of a few labor. Each labor situation includes route of a job normally, also can include route of a few jobs. To improve productivity, machine a few labor situations that machine the surface at the same time with a few cutting tool, call complex labor situation, also can regard situation of a labor, for example, assorted drilling machine machines poriferous casing aperture. (5) cutting tool of treatment taking a knife is being machined apparently the labor situation part that treatment completes calls a knife. For example axis kind if the spare parts wants the metallic layer that cuts very thick, need to divide second cutting, at this moment every cutting is called take a knife. Because this is below the premise with cutting speed and changeless feed,cutting tool finishs primary feed motion to be called take a knife. Graph 1-2 is a belt closes partly the process example that axis of keyway a flight of stairs produces a type two kinds, can see respective working procedure, installation, industry from which, labor situation, take the concern between the knife.
