Summary of the invention
The present invention aims to provide and a kind ofly can reduce layering as far as possible, can satisfy the method for FMC layering processing FM of the needs of programming and processing again fully.
In order to reach this purpose, the present invention adopts following technical scheme:
A. make foundation;
B. paste process redundancy, scaling water by the correlation technique regulation, is considered process redundancy and washing shrinkage according to casting dimension size and casting material, and is examined its processibility;
C. layering; According to actual conditions conplane structure is divided on different layers; Wherein ground floor is a base portion; The second layer is the profile part, Wedge mechanism install table top and waste material cutter install table top then through separate, rotation, translation, and the method for tying be combined in the new erecting bed surface model of formation on the foam blank;
D. machining programming and procedures sheet according to the model layer after dividing well, can be worked out each layer pros and cons job sequence respectively;
Each layer bubbles model blank size blanking of e. indicating according to procedures sheet;
F. follow procedure carries out data processing;
G. the workman pastes, and makes The model.
Wherein, blank size preferably uses the size that satisfies current material, to reduce workman's blanking and the time of pasting cost.Lift height is not less than 100mm at least in addition.According to different parts, can adopt rotation and methods such as knot, separation or translation to realize layering during layering.
The present invention can reduce layering as far as possible, can satisfy the needs of programming and processing again fully.Reduce workman's working time, thereby saved human resources, reduced cost.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done more detailed description.
The invention discloses the method for a kind of FMC layering processing FM.The present invention adopts following steps to carry out:
A. make foundation;
B. paste process redundancy, scaling water by the correlation technique regulation, is considered process redundancy and washing shrinkage according to casting dimension size and casting material, and is examined its processibility;
C. layering; According to actual conditions conplane structure is divided on different layers; Wherein ground floor is a base portion; The second layer is the profile part, Wedge mechanism install table top and waste material cutter install table top then through separate, rotation, translation, and the method for tying be combined in the new erecting bed surface model of formation on the foam blank;
D. machining programming and procedures sheet according to the model layer after dividing well, can be worked out each layer pros and cons job sequence respectively;
Each layer bubbles model blank size blanking of e. indicating according to procedures sheet;
F. follow procedure carries out data processing;
G. the workman pastes, and makes The model.
Wherein, consider the range of work of lathe, receive the restriction of foam machining tool working ability, aniseed can not surpass 4000mm * 2000mm * 700mm.Because of foamed material is a bulk material, size is 2000mm * 1000mm * 500mm then, so the size of each blanking is preferably used the size that satisfies current material, to reduce workman's blanking and the time of pasting cost.At first will think about the digital control processing part in addition during layering and make part by hand, for example some can not adopt manual mode to accomplish at the lightening hole of correct position.Wherein the hanger part program is complicated, and after digital control processing was accomplished, presentation quality, changed by the workman and makes by hand so should avoid numerically-controlled machine processing as far as possible not as making by hand.Lift height is not less than 100mm as far as possible, otherwise processing difficulties.
Must partly post surplus to machined surface before the layering, prevent obscuring of machined surface and non-machined surface after the layering, miss process redundancy, like the bottom surface, lean against face, guide plate installed surface, spigot surface, spring and table top etc. is installed, and is considered washing shrinkage.
Consult Fig. 1, Fig. 2, concrete delaminating process is described with the instance of a FMC bubbles model layering processing.The analytical model structure can be found out from figure, and because of the mould fore-and-aft direction skids off 25 ° big inclined-planes 5 for the deburring waste material, and the scrap cutter that has the wedge deburring to use on the inclined-plane 5 is installed table top 6 and Wedge mechanism installation table top 4.At first stick process redundancy, the profile surplus is then guaranteed by job sequence because of the curved surface complicacy.If, can cause following result: 1. the too thin bad processing in inclined-plane 5 by the direct integral level layering of classic method; 2. the middle layer has many independent ribs 1 that have been cut off.Therefore, for fear of this rough sledding of appearance, and consider the machining tool range of work and foam blank size.Therefore, we have taked another kind of job operation.
Consult Fig. 3～Fig. 6, adopt scientific approach to carry out layering.Wherein ground floor is a base portion 2, and the second layer is a profile part 3, Wedge mechanism install table top 4 and waste material cutter install 6 of table tops through separate, rotation, translation, and the method for tying be combined in the new erecting bed surface model 7 of formation on the foam blank.Last hanger 8 then adopts the mode of making stickup by hand to handle with some small boss.
After layering is accomplished, follow machining programming and procedures sheet.According to the model layer after dividing well, can work out each layer pros and cons job sequence respectively.Each layer bubbles model blank size blanking of indicating according to procedures sheet then, follow procedure carries out digital control processing.The workman pastes the making The model and gets finished product.
The present invention can reduce workman's working time, saves human resources, thereby has reduced cost.
